No commercials callers please this is a genuine private sale.

The BMW 1M was among the first proper M cars to use turbocharging; it may have vexed the purists, but its engine is a belter and a big part of its appeal. Driving the rear wheels via lovely slick six-speed manual gearbox is a 335bhp twin-turbo 3-litre straight-six engine. In the 1495kg 1M Coupe, it yields a 4.8sec 0-60 time and an electronically limited 155mph top speed, though we've seen an indicated 170mph on derestricted German autobahn.

There's an MDM button, which partially or fully deactivates the stability and traction control systems, while an M button alters the throttle response. Unlike bigger M cars, this button isn't programmable; the upside is a lack of technological confusion when you simply want to get on with the business of going fast.

It also boasts a proper limited-slip differential, where its nearest thing to a successor, the BMW M135i, gets an electronic setup.
