. . . It is a Renault.
Any more details? Year, model, ???
Does not look right for a Renault, and they were not really into making 2 seat coupés (it at least looks like a 2 seater)... The rear and that split rear window has me thinking Karmann for some reason, or Alfa. Without a higher definition or a front view, I'm stumped...
I was thinking the same thing, Daniel. Maybe even an old Aston Martin, but I can't find another picture online that looks exactly like it (especially the rear window). If you click on the picture, it gets a little bigger, but not much. Sorry about no views of the front, but it's dangerous to drive and snap pictures at the same time, even from a crappy cellphone camera.
I'm told by "Healey Z" at the British Car Forum that it's an early 50's Alfa Romeo 6c 2500 ss cabriolet with a hardtop.
Looks like one (http://imageshack.us/photo/my-images/18/alfaromeo6c3.jpg/ for a coupé)
