Before reading though the thread, I was going to say a '65 Mustang, or to be more specific, a '65 Shelby GT350, with Le Mans Blue stripes over the Wimbeldon White, but alas, I suppose it's a pony car.
Ah well.
Out of the list, I'd probably go with the '69-'70 Ford Mustang. Something about those body styles just grabs me. I guess it's the fact that they look so much more agressive than the ones from five (and 1/2) and 6 (and 1/2) year before them. I much prefer the rear decklid on the one shown over the Mach 1's though. I've never liked how the slope fell all the way to the rear of the car. Gotta have a flat section in there. That, and the louvers are just so cool!
Is there a specific name for the variation in the rear decklid between, say, the Boss 302-esc and Mach 1's?
