Overview

The original Mazda MX-5, the NA or Mk1, did something no other car managed in 1989: it made the simple, affordable roadster desirable again. Inspired by the classic British sports cars of the 1960s but engineered with Japanese reliability, it arrived in the UK in 1990 to instant acclaim. The 1.6-litre twin-cam engine produced 115bhp, the weight distribution was a near-perfect 50:50, and the whole car weighed barely 950kg.

Driving one is still a joy more than three decades on. The steering is light and full of feel, the five-speed gearbox has one of the best shifts ever fitted to an affordable car, and the chassis communicates everything through the seat of your trousers. It is not fast by modern standards, but on a twisting B-road few cars at any price are more fun.

When buying, rust is the number one enemy. Check the sills, inner and outer rear wheelarches, the base of the windscreen pillars and the front wing bottoms very carefully, and inspect underneath for rot around the floorpan. Japanese Eunos Roadster imports are mechanically identical and often better preserved, though UK cars have the more desirable mph speedometer. The cambelt is due every 62,000 miles, and a tired vinyl hood is a bargaining chip rather than a deal-breaker.

UK price from: £6,500

Frequently asked questions

Where do Mk1 MX-5s rust?
The classic rot spots are the inner and outer rear wheelarches, the sills (especially where they meet the rear wings), the base of the windscreen pillars and the lower edges of the front wings. Get the car on a ramp and probe underneath — surface bubbles often hide serious rot. A clean, rustproofed car is worth paying a premium for.
Should I buy a UK MX-5 or a Eunos Roadster import?
Mechanically they are near-identical. Eunos imports often have less rust and lower mileage, but UK cars have mph dials and sometimes better history. Insurance is straightforward for either. Buy on condition, not origin.
When does the cambelt need changing?
Mazda specifies every 62,000 miles on the 1.6. It is a non-interference engine, so a snapped belt strands you rather than wrecking the engine, but factor around £200-250 at a specialist if it is overdue.
Is the Mk1 MX-5 a good first classic car?
Arguably the best. Parts are cheap and plentiful, every job has a YouTube guide, and the owners'' club is huge and friendly. It is reliable, fun and appreciating in value — the classic-car trifecta.
What does it cost to run a Mk1 MX-5?
Insurance is cheap, VED is the historic-vehicle rate or standard classic rate depending on age, and a service costs around £150 at a specialist. Budget for rustproofing and the occasional hood, and it is one of the cheapest classics to own.
