Now, IF you select only 'Muscle Cars', I will say the top three would be (in my opinion), are:
1970 Olds 442 W-30, 455 cid.
1970 Buick GS Stage 1, 455 cid.
Tie: 1969 1/2 440-6 Road Runner/1970 Mercury Spoiler, 429 SCJ.
Why these?
1. Styling
2. Performance
3. Just plain 'ol neat.
4. All around the best. 1/4 mile, wow factor, and roomy/comfortable (maybe except the Road Runner).
And, most important: I would be proud to have all of them in my garage!
Again, my choices.
