Here’s everything you need to know before you invest your hard-earned cash into a Mazda MX-5 NC (also known as a Mk3). Launched in 2005, the NC was an all-new model compared to its predecessor, with much-improved safety thanks to more airbags and traction control to prevent spinning out in the rear-wheel drive roadster. The third-gen MX-5 also introduced more luxury and comfort to the interior, which makes it far easier to live with as a daily driver than the previous incarnations.
Despite the MX-5 NC traditionally being the least favourite amongst enthusiasts, the Mk3 model is gathering a loyal following as a daily driver thanks to the leap forwards in safety and driver comfort. The Mk3 MX-5 was (and still is) also a bit of a track-weapon because the rear suspension was a totally new multi-link design upon launch.
Is the Mazda MX-5 NC the perfect cult classic to modify on a budget?
The MX-5 Mk3 is rapidly becoming one of the default choices for enthusiasts, and for good reason. If you’re on the hunt for an MX-5 and you want to know exactly what to look out for, then you’re in the right place.
If you’re into tinkering with cars, this little convertible roadster’s got the chops to keep you engaged and entertained on the road. The third-gen MX-5 is known for its featherweight construction, which makes it a blast to fling around twisty corners of the UK’s roads. Plus, it’s a dream for modding without beefing up the weight too much.
The Mazda MX-5 NC, NC2 and NC3
While the MX-5 Mk3 is the third instalment of this generation from Mazda, there are a few iterations you should know about if you’re in the market for buying a second-hand MX-5:
- Mazda MX-5 Mk3 NC: 2005-2008 model offered with a rounded grille (similar to the Mk1 and 1998-2000 Mk2) as standard. In 2006, buyers got the Power Retractable Hard Top option.
- Mazda MX-5 Mk3.5 NC2: Late 2008-2012 got an updated grille and headlights, more like the 2001-2005 Mk2.5 MX-5. Engines were updated and 2.0 rev limit increased from 6,750rpm to 7,000rpm.
- Mazda MX-5 Mk3.75 NC3: 2013-2015, the grille was enlarged and more angular, with revisions to the headlights and fog lights. This is commonly referred to as the facelifted NC as its upgrades were mostly aesthetic revisions.
Mazda MX-5 NC: Soft-top or Hard-top?
When it comes to roofs, you have two options: the soft-top or hard-top metal folding roof. Like other soft-top convertibles, you’ll get a lighter sports car if you opt for a soft roof. But you’ll also have to put up with increased road and wind noise, as well as potentially more maintenance to keep the Mohair roof in good nick. For example, the soft-top NC models will need to be periodically re-waterproofed. The biggest gripe from MX-5 owners of the hard-top model is the increased weight.
There are big discrepancies as to how much extra weight the hard-top roof is reported to add to the MX-5 NC, but Mazda says the folding metal roof adds just 36kg of weight. While this may be conservative, it’s best to drive both options if you haven’t got a preference, as this is the most straightforward way to make a like-for-like comparison between the two models.

Mazda MX-5 NC: Issues to look out for
The first issue to look out for when buying a used MX-5 NC is the rust. Like its predecessors, the NC model seems to have inherited their penchant for chassis rust. Mk3s MX-5s are prone to rust in the same place as the Mk1 and Mk2 Mazda MX-5, in front of the rear wheel behind the arch liner.
The rear subframe braces also rust, and are an MOT failure, which is why we offer genuine replacement rear subframe brace bars for the MX-5 NC. Really early models are known for spinning engine bearings, too, so keeping the oil topped up is even more important than usual.
When you’re looking at buying a used MX-5 NC, especially the NC 1 (pre-facelift), make sure to check the following components, too:
- Wheel arches for rust blisters. Look at the bonnet edge for lacquer peel on top and underneath. Check for the same issues under the boot lid around the number plate lights, as some models historically struggle with corrosion here due to water pooling
- Check under the car for corrosion, especially down where the rear part of the sill meets the lower wheel arch and under the car
- The general condition of the tyres to see that they’re in decent condition and will pass an MOT. They should all have equal wear, and no bulges or cuts. The brand and size should also be the same across all four tyres, especially the tyres on the same axle
- Check the engine has the correct oil level
- Check the service history and MOT history on Gov.uk
- Make sure the inside is dry as leaks can occur. Wet carpets are a tell-tale sign of water ingress from the dashboard or through the roof
Test drive the car, we insist. It’s essential that you get a feel for how it drives at slow and fast speeds. Steering should feel light and responsive; there should be no whining, vibrations or other unusual noises. On that note, check the brakes for responsiveness and noise (like sticking brake calipers), too. No one wants to buy a car that immediately needs significant work done to bring it up to scratch.
Mazda MX-5 NC: What to check when buying a used model
We’ve covered the issues you should check any potential MX-5 Mk3s for if you’re in the market to buy, but there are some extra checks that we’d advise for buying any used car to ensure it’s a solid investment:
- Documents to check when buying a used car include the V5C registration document to tax the car. Ensure this document is valid and that it matches the VIN, too
- Does the mileage, age and appearance of the car look consistent? If not, make sure you’re not being conned into buying a used car with clocked mileage, as this is an increasingly problematic tactic in the used car market. Check recorded mileage on service records, MOT certificates etc
- Check for signs of inconsistent gaps between panels or mismatched colours, as these could be signs of repairs from an undeclared accident. Similarly, check for mismatched paint colour and finish on the car
- Is the tyre inflator/sealant kit in serviceable condition, and is the jack and other necessary tools present?
- Check that all lights and windscreen wipers/washers work correctly
- Check that the oil warning light goes out as soon as the engine starts
- A noise when you press the clutch pedal or a high biting point could mean that repairs will be required soon, as it’s been worn/burnt out
- Locks, windows, roof controls, mirrors, air-con and other electrics
- Have you got all the keys and do they work? Check the handbook to see which keys were provided when the car was new
- Check that the locking wheel nuts are fitted
- Run a reputable vehicle history check. You’ll need the registration number for this, but it’s very straightforward and will tell you if the car is stolen, written off or has outstanding finance
Mazda MX-5 NC: Aftermarket Modifications
Thanks to the MX-5’s cult following, there’s also a boatload of aftermarket goodies out there that won’t put a dent in your wallet. Whether you’re after sportier suspension or a louder exhaust, you’ll find plenty of affordable options — including our stock of Tein Enduropro Plus Dampers or Eight Nine Cat Back Exhaust System.
The relatively simple design of the NC means even rookies can handle basic mods with nothing more than a trusty set of tools, so don’t fret if you’re a newbie to this model. Another great part of owning a MK3 MX-5 is that it puts you in great company, with an enthusiastic cult following that’s always itching to share their knowledge with the MX-5 community. And that’s especially true for the team at BOFI Racing, who are always willing to give tips and tricks when it comes to your build.
Buying a used MX-5 NC/Mk3: 1.8 or 2.0-litre Engine?
Now, let’s talk engines. The choice is narrow, so you only get to choose between the 1.8-litre and the 2.0-litre. The Duratec engine, which the MZR is based on, is highly tunable and is used in Morgan sports cars, too. It was designed by Mazda, in partnership at the time with Ford. If you’re buying privately, then we suggest you ask the owner about oil consumption, as it’s a known issue on some of these models.
The smaller 1.8-litre is paired with a five-speed gearbox, while the bigger one gets you a limited slip differential to play with. On top of that, 2.0 Sport models got an extra gear. The 1.8 pushes out 170Nm, while the 2.0’s got 186Nm under the hood. Neither will offer the torque nor power of something like the Nissan 370Z, but driving the NC will always put a smile on your face.

The best modifications for a Mazda MX-5 NC/Mk3
If you’re planning to soup up your NC (and why shouldn’t you?), then you’ll potentially already have some idea of what you want to upgrade from stock. But, here’s our rundown of the best modifications you can make to your MX-5 Mk3:
Suspension
Coilovers, to be specific. The MX-5 has many wonderful things going for it, but it certainly doesn’t offer too much ride comfort. Having been raised to improve pedestrian safety in line with EU standards, both the appearance and handling of the NC were negatively affected — with some drivers finding there’s too much body roll pre-mods.
Coilover suspension is a type of sports suspension that’ll allow you to adjust your NC’s ride height and damping characteristics, comprehensively upgrading the handling — making it ideal for drivers who want something that rides harder on track and softer on the commute.
BOFI Racing’s recommendation is the MeisterR Sportive coilovers, delivering renowned ride quality at a budget-friendly price. Aluminium top mounts and electroplated damper bodies are included, so these MX-5 coilovers will last on harsh UK roads.
Exhaust system
When it comes to exhaust system upgrades, we recommend the ISR cat back exhaust. The ISR Performance Circuit Spec Cat Back Exhaust is designed to be used with a Mazda MX-5 Mk3, offering a thunderous tone and stainless steel durability.
Everything else
Our last two MX-5 NC mod recommendations include one for added comfort and one for better performance. So, without further ado, we suggest the K&N intake system and the Jass Performance seat lowering brackets.
Each K&M induction kit is designed to provide power throughout the RPM range. The extra surface area of the high-flow air filters provides more airflow at lower restriction, meaning your MX-5 will have greater horsepower and torque in its back pocket, plus a healthy dose of intake noise for an immersive driving experience.
One of the cheapest modifications you can make to a little car like the NC is seat height adjustment. Jass’ seat lowering adaptors mount the stock NC seats in their lowest possible position while maintaining full seat travel, which makes a considerable difference to the driving position.
Buying a Mazda MX-5 NC (Mk3): Our Verdict
We’re obviously a little biased in this regard, but our verdict for this special little roadster is very positive.
What the MX-5 NC potentially lacks in luxurious interior quality and best-in-class speed or fuel economy, it makes up for in versatility galore. Want to tear up the track? Go for it. Feel like hitting the twisties on a warm Sunday evening? The MX-5’s MK3 is always up for the challenge.
With the right upgrades, you can tune the little roadster into exactly what you desire in terms of comfort, performance and style. Another pro is that, even with a few tweaks under the hood, you can trust the MX-5 to run reliably, mile after mile. It’s a Mazda, after all.
And, finally, for the more financially astute among us petrolheads, the MX-5 retains its value despite being an older car. Despite all the mods, the NC tends to hold its own in the resale game. So, if you ever decide to part ways, you can bet you’ll get a decent chunk of change back in your pocket for this modern classic.
Today’s drivers looking for a fun, relatively inexpensive modern classic will find huge appeal in the back-to-basics, fun driving experience found in the third-generation MX-5. As long as you don’t need more than two seats, and you aren’t looking for supercar performance, the MX-5 Mk3 could be the perfect fit for you. And, if you’re a bit worried about buying an older model, have faith that you can find a near-endless supply of helpful information from other MX-5 Mk3 owners in online forums.
