For me it's got to be a BMW 850Csi (E31) from the 90's... one of the best examples of a car sporting popup lights, in my opinion. Un-officially a 'detuned' M8 with the special 'S' engine designation... slow by today's standards, but what a motor.

There's one on AT currently for about £55k, and as they're so few and far between I can't see it depreciating - and if I was going to spend that much on a car, I doubt it would be a BMW... so that's why I shelve it under the 'out of reach' category.
