I have had some muscle cars and some strong performers that they do not really consider muscle cars but were actually the cars that I liked the most. I have had a couple tweeners but nothing worth mentioning.
In order:
1966 Impala - Only had it a short time and sold it for
1970 GTO - Ran like a raped ape till the day I slammed it into a curb at about 90mph after going airborne over a median
1970 Pontiac Grand Prix - Probably my favorite car that ran super and the interior was like a jet cockpit extremely funtional and super comfortable but sold for a
1969 Triumph 650 Trophy still working on the restore
1969 GTO - needed an engine and some resto, sold to buy
1969 Grand Prix - Super project car that I was fixing it all up, Black leather interior, body was solid but 428 engine smoked, built a 455HO engine for it after doing tons of research on best performance tips and mods. Installed it and had the transmission rebuilt, 3.55 gears, then I got married and ended up selling it to a buddy of mine for down payment on a house before I ever had a chance to start it up. He got it running and brought it over and threw me the keys one day and said take it for a ride. I did and have been kicking myself in the A*# ever since. I did tons of research before I ever built the engine and it all paid off, too bad it was for someone else. Ever since then its been all Toyota trucks and 4Runners. I still have Pontiac motors around that someday I want to find an old Trans-Am, GTO, or Grand Prix and do a ground up restore that will run like a scalded dog!
Long rant but I sure miss the days that you could buy a muscle car or great performing car for a couple hundred dollars(Never paid more than $750.00 for any of the cars) or there abouts and run a car with true soul like others have stated here. I agree cars today just don't have the soul like the cars of yesteryear.
