1986 BMW M5 review from UK and Ireland

I jet-washed the engine and got water in the electrics, the car misfired for the weekend and returned only 20MPG during a trip to the Brecon Beacons from Epping.

Had to replace the exhaust system (£680), propshaft donut and bottom suspension arms (ball-joints).

The boot-lid seal leaks despite being replaced.

The instrument cluster and service lights mysteriously failed after being serviced by a BMW 'expert' - not a dealer, ever since I have relied only on BMW dealers.

I've never owned a BMW before nor wanted to, but this car has radically altered my view on that.

The service staff at Godfrey Hall in Coventry are extremely polite and efficient plus a 6000 mile service costs less than £100.

Other spare parts are pretty expensive but the car has been so reliable that average running costs are comparable with anything I've owned previously.

Insurance is astronomical as the car is a group 20, but fuel economy is surprisingly good at 25.4MPG average. Unlike later M5's the car does not have a speed limiter and a top speed of 165MPH is supposedly attainable.

One downside is that the leather Recaros are not as comfortable as they look - although 12-way electrically adjustable, they don't have adjustable lumbar support and I've experienced back-ache on some long journeys.

The worst thing about the car is that it has raised my expectations so high that I have no idea what to buy next - anything would seem disappointing compared with the 'M'.
