Few cars offer the same mix of fun, reliability, and community spirit as the Mazda MX5. Since its launch in 1989, the MX5 has built a passionate following here in the UK, thanks to its lightweight handling, back-to-basics design, and timeless charm. Whether you're looking for a weekend toy, a show-ready project, or a daily driver with character, there’s an MX5 for you.
But with four generations and over three decades of production to choose from, buying a classic MX-5 can feel a little daunting. That’s why we’ve created this helpful guide, bringing together key considerations for each MX5 generation (Mk1 to Mk4) to help you make the right choice.
First Things First, What Defines a ‘Classic’ MX5?
The term ‘classic’ is often associated with age, but for MX5 owners, it also means character. Most agree that the Mk1 and Mk2 now firmly fall into classic territory, with the Mk3 ageing gracefully into modern classic status. Even the Mk4 (launched in 2015) is becoming a future classic, especially limited-edition models.
Whichever generation you’re considering, the MX5 offers excellent value, if you know what to look for. Let’s break it down, generation by generation.
Mk1 (1989–1998) The Original Icon
Often referred to by its chassis code “NA,” the Mk1 is the car that reignited the world’s love for small, rear-wheel-drive roadsters. With its pop-up headlights, featherweight chassis, and no-frills design, the Mk1 is the purest MX5 experience you can buy.
What to Look For:
· Rust! It’s the Mk1’s Achilles’ heel. Common spots include sills, wheel arches, chassis rails, and around the front wings. Look underneath, surface rust is manageable, structural rot is not.
· Leaky hoods - Expect original soft tops to be past their best. Replacements are available and often improve both looks and comfort.
· Sticky pop-up headlights - Often just a relay or motor issue, but worth checking.
· Service history - These cars are bulletproof with maintenance, but abuse or neglect can lead to oil leaks, tired suspension, or worn clutches.
· Aftermarket mods - Some are great, others less so. Watch out for poor DIY jobs or chassis modifications that can impact handling.
Why Buy One?
· It’s the lightest, simplest and arguably most rewarding MX5 to drive.
· Rising classic status means values are holding strong.
· Great aftermarket support (especially from us at MX5parts!)
Mk2 / Mk2.5 (1998–2005) Familiar Feel, Modern Touches
Known as the NB, the Mk2 built on the success of the original by refining the ride and comfort while keeping the driving spirit intact. It lost the pop-ups but gained better brakes, revised suspension and a slightly more mature look.
What to Look For:
· Rust (again) - The sills and rear arches are particularly vulnerable on Mk2s. Even cars that look clean outside may be hiding corrosion underneath.
· Chassis rails - These can rot from the inside out and often go unnoticed.
· Suspension wear - Listen for knocking over bumps or vague handling. Bushes, springs, and dampers may need replacing.
· Cooling system - Radiators and hoses can degrade with age, leading to overheating issues if neglected.
· Electrical gremlins - Generally reliable, but older cars can have sticky windows, dodgy immobilisers or central locking faults.
Why Buy One?
· More comfort and safety features than the Mk1, but still lightweight and responsive.
· The 1.8-litre versions (especially the Sport models) offer great value performance.
· Huge parts availability and affordability.
Mk3 / NC (2005–2015) The Modern Classic Sweet Spot
The Mk3 took a bold step forward with a new platform, bigger 1.8 and 2.0 engines, and more interior comfort. It’s heavier than previous models but still retains that familiar rear-wheel-drive playfulness. Many see the NC as the best “daily-driver” MX-5.
What to Look For:
· Rust (still!) - Especially on early NCs. Check rear arches, under the battery tray, and around the rear subframe.
· Front suspension - Drop links and lower arms can wear, leading to clunks and vague steering.
· Clutch feel - High biting points or judder may indicate wear or slave cylinder issues.
· PRHT roof (if fitted) - The powered folding hardtop is brilliant when working, but make sure it operates smoothly and seals properly.
· Engine oil level - The 2.0 engine is strong but doesn’t like being run low on oil. A regular check is essential.
Why Buy One?
· Everyday usability meets MX5 charm.
· Prices are excellent, especially for low-mileage examples.
· One of the best “bang for buck” modern classics on the market.
Mk4 / ND (2015–Present) The Lightweight Revival
The ND brought the MX5 back to its roots, shedding weight, adding tech, and delivering an agile, responsive drive in a modern package. While newer and still in production, early Mk4s are now hitting prices that make them a tempting classic-in-waiting.
What to Look For:
· Paint quality - Some early NDs had soft paint that chips easily, particularly on the Soul Red models.
· Gearbox issues (early 2.0 models) - Affected some 2015–2016 cars. Mazda improved the design after recalls.
· Infotainment glitches - Screen freezing or nav issues can occur, often fixed by a software update.
· Wheel alignment - Lowered or hard-driven cars may suffer from uneven tyre wear or nervous handling.
· Battery drain - Some owners report battery drain issues if the car is unused for long periods. A trickle charger can solve it.
Why Buy One?
· Near-perfect balance of old-school MX5 character and new tech.
· Lightweight, efficient, and easy to live with.
· Early NDs now offer great value, especially 1.5 models with fewer driver aids for a purer feel.
Final Buying Tips
Whichever generation catches your eye, keep these general tips in mind:
· Rust is more important than mileage - A well-looked-after 100k-mile MX5 is usually a safer bet than a rusty 40k-mile one.
· Get underneath - If you're serious, get the car on a ramp or at least look under the sills.
· Join the community - Forums and MX-5 Owners Club events are a great way to find honest cars (and get honest advice).
· Factor in upgrades - A decent budget for tyres, brakes, and bushes can transform even the most tired car.
· Use the MOT history tool - It gives a useful snapshot of past advisories, failures, and potential hidden issues.
