Reverse car spec search website?

There are umpteen sites that let you look up the detailed specs and estimated value of a car given the make. model and year. Are there any sites that work the other way? e.g. I want a list of cars with X doors, >Y O-60, >Z MPG, etc? I'm sure I used one last time I was car hunting (10 years ago!) but this time I've drawn a blank. Ideally it would cover old models not just in-production, but anything would do for a start!

Ta!

Only those classified websites mate nothing more special than that.

Pistonheads also does this.
