BUYING TIPS

1 ENGINE WEAR

‘Worn rotor tip seals’ is a phrase that RX-7 enthusiasts dread. It’s virtually always the first component to wear in the engine, necessitating a rebuild, and while the parts aren’t expensive, it’ll require a specialist to fit. Look out for poor starting – particularly from hot – and excessive fuel consumption.

2 HOW’S THE BODY?

The RX-7 is much better rustprotected than most Japanese cars of the period (simply put, Mazda actually tried), but superficial areas seem to be particularly vulnerable, with the suspension mounting points the only structural area to commonly corrode. Check wheel arches, sills, door bottoms and any panel that has bits of plastic trim attached to it.

3 DOES IT STOP PROPERLY?

The front discs are known to be a bit on the fragile side in the hands of enthusiastic drivers. Check that it stops in a straight line, of course, but thoroughly inspect the surface of the discs too.

4 DRIP, DRIP, DRIP

Check where the car has been parked for oil leaks and don’t accept the age-old ‘oh, they all do that’ answer. Anything but a very small leak is grounds for a rebuild, as the oil plays a major role in cooling, as well as lubricating, a rotary. The oil cooler piping and rotor housing O-ring are particularly susceptible, with the latter a major bill.

Rotary engine’s compact proportions are key to the RX-7’s dynamics.

UK RX-7s only came in one trim level, but the standard equipment list was huge.
