For me, I'd have to say '70 Challenger, and '71 Cuda.
I still don't like the grills for the '71 Chally. Dunno why, but I guess they don't say 'Muscle Car' for me. IMO.
I never used to like the billboards on the '71 Cuda, but I've grown. I still prefer the '71 Cuda, and would want a 340 powered 'vert for cruising, the 'vert would be 'stripe delete', but a hard top Cuda needs billboards. :thumbs:
I'm still tempted to try to mate a '70 grill to my '72 Chally.
