What classic muscle car that wouldn't break the bank would you consider for a daily driver?

Life's too short to drive a "meh" car...

Here's the setup: You've got your beautiful classic in the garage already and take it out on nice days. The problem is that you still have to work, so it's yet another 5-mile ride to the daily grind in your wife's old, hand-me-down 2014 Chevy Sonic.

You ain't feeling it. Crossing the lot at the end of a hard day only to climb into your wife's old 4-door, subcompact sedan is making you feel like a 54 year old King Theoden as you stand there holding the keys and muttter under your breath, "How did it come to this?" You gotta do something.

The question: What American sports car, preferably something older that you don't see 100 of everyday, that's not impossible to find, that you can pick up without having to sell a kidney (think "budget" here), would you consider? It's gotta give you joy when you see it, kinda like how you feel when you see your beloved dog waiting for you on the porch as you pull in the driveway.

All makes and models are on the table: Ford, Chevy, Dodge... all are welcome. It doesn't have to be a '60's or '70's car either unless you can find a solid, dependable driver under $20k. (Yeah, that's about as real as Sasquatch, Unicorns, and North Dakota...)
