Mazda MX-5 Mk1 and Mk2 (1989 to 2005)

Why people buy one

• Light, balanced and rewarding to drive, with a precise five-speed gearbox (six-speed on some Mk2 versions).
• Twin-cam engines are reliable when serviced, and the cambelt on the Mk1 is a non-interference design, so a snapped belt should not wreck the engine.
• Huge production (431,506 Mk1s and around 290,000 to 300,000 Mk2s, by source) means mechanical and service parts are easy to find.
• A wide choice of models, from basic 1.6s to well-equipped 1.8s and many special editions.
• The MX-5 Owners Club is large and active, with a strong technical forum and regional groups.

What to weigh up

• Rust is the biggest problem on both generations and past repairs are often poor. The Mk2 adds a weakness in its double-skinned front chassis rails, which can rot from the inside.
• Many UK cars are Japanese Eunos Roadster grey imports. Classic & Sports Car says their rust protection is inferior, while Hagerty UK notes they benefited from unsalted Japanese roads, so judge each car on its own condition.
• On imports, the speedometer was often changed from kilometres to miles, so recorded mileage may not be provable.
• Very early 1.6 engines have a short-nose crankshaft whose pulley can work loose and damage the crank.
• Many cars have been modified with lowered suspension, aftermarket wheels and add-on styling. A claimed BBR Turbo or limited edition needs its paperwork checked, as badges and decals are easy to add.
• The cabin is small, and soft tops leak once worn or if their drains block.

Where they rust

• Rear sills, especially at the bottom of the rear wings just ahead of the rear wheels, where water collects if the hood drain tubes block.
• Rear wheelarches, inner and outer, and the floor next to them.
• Inner sills, which are usually rotten if the outer sill is crumbly.
• Front chassis rails on the Mk2, which are multi-layered and mostly hidden.
• Bottoms of the bolt-on front wings and the area above the front bumper.
• Front floors, from long-term hood or door leaks.
• Door jambs under the kick plates on early cars, and occasionally the base of the windscreen pillars.
• Pressed-steel suspension arms, which corrode from road salt.
• Jacking points, boot floor and battery area, particularly on the Mk2.

Mechanical weak spots

• Engine: on early 1.6s, a pulley with four slots indicates the short-nose crank, while the later eight-slot pulley is regarded as safer; check for wobble at the crank pulley.
• Head gasket failure usually follows overheating from a silted radiator. The alloy head needs corrosion inhibitor in the coolant, and oil leaks onto heater hoses (from the cam angle sensor on the Mk1 1.8, or the back of the head on the Mk2 1.8) can split them.
• Cambelt: Classic & Sports Car gives five to six years or about 54,000 to 60,000 miles depending on model; ask for proof it has been done.
• Mk1 hydraulic tappets may rattle briefly on start-up; the Mk2 uses shimmed tappets that need adjusting if noisy.
• Gearbox: a stiff change often needs fresh oil in the remote extension rather than a rebuild.
• Suspension and brakes: clonks from anti-roll bar drop links, broken coil springs, worn bushes and dampers, and sticking rear calipers on little-used cars.
• Electrics: check the pop-up headlamps, electric windows and immobiliser. Imported Eunos air conditioning may use the old R12 refrigerant, which is costly to repair.

At a Mathewsons viewing

• Check the VIN against the V5C: UK-market cars have chassis numbers beginning JMZ, while Japanese Eunos cars begin NA. On an import, ask for its import and registration paperwork and treat the displayed mileage with caution.
• Look for Eunos clues such as a narrower, taller rear number plate recess and different badges, and confirm the V5C describes the car you are looking at.
• With a torch, look at the rear sills ahead of the rear wheels, the rear arches and, on a Mk2, up at the front chassis rails behind the bumper for rot, filler or fresh underseal.
• Lift the carpets and press the floors for damp, and check the hood for tears, a clouded rear screen and blocked drain tubes.
• Open the bonnet and look at the crank pulley, coolant colour and oil under the filler cap; if staff start the car, listen for persistent tappet noise and watch for smoke, but do not assume it will be started.
