BMW M3 - a supercar refined - Verdict

£50,000 is a lot for any car, but this one justifies every penny.

It has a sublime chassis that's well balanced and responsive, an engine that just keeps on pulling, and phenomenal grip.

It's comfortable and well equipped, and is as eminently suitable as an everyday car as it is at home on racetracks.

Fuel economy is unlikely to reach claimed figures, tyre wear will be heavy and company car bills will be stiff - but enthusiasts won't care, because it's a sensational performer.
