1. Aston Martin One-77

Got a spare 1.2 million and looking for a car?

If the answer's yes, it might be at the Paris motor show.

Then again, it might not. We were never sure, because Aston Martin refused to take the covers off its One-77 throughout the duration of the show.

What we do know is that it's set to go on sale next year and is expected to be a front-engined coupe with hand-formed aluminium panels over an all-new carbon fibre monocoque chassis.

Power will come from a 7.0-litre V12 rated at about 650bhp, which should make the One-77 faster than any existing Aston and push top speed beyond 220mph.

Sign up early, though, and you won't just be buying a car, because you'll also be able to get involved with the design and development of the car.

Buyers will get access to the companys top designers and engineers, will have cars minutely tailored to their own requirements, and will even be encouraged to take part in suspension development.

The One-77 name, which reflects the fact no more than 77 versions of the car will be built, will not be used for the final car.

Why we didn't like it Putting a (presumably unfinished) car under a blanket and pretending it is a 1.2 million supercar is a bit shabby, frankly.
