The classic BMW M5 E28 model was one of the first motors in a long line of understated performance saloons, according to Andrew English.
In an article for the Daily Telegraph, the writer admires the engine, a down-tuned version of the 3.5-litre, twin-cam, 24-valve straight six that was also used in the M1 supercar.
The European version could provide classic car drivers with 286bhp at 6,500rpm and was able to hit a top speed of 150mph, he pointed out.
Hailing from between 1985 to 1987, it could also go from standstill to 60mph in 6.2 seconds
"Open up the six throttles and the M5 took off like a scalded stoat. In the days before traction control it could lay down an avenue of tyre smoke," Mr English wrote.
Classic BMW fans could look to join the BMW Car Club of Great Britain & Ireland, which was established in 1952 by Ralph Hewitt.
