While for the most part i strongly agree with you, but there still are a few out there that are okay.
As for good-ol'-american muscle, hands down, is the toughest to beat. Look at the classic lines of many older car amkes like Pontiac (60s), Chevy (tri-fives), Ford (50s-60s), AMC (66-69), Chrysler (60s), and so on; those are true cars. I dig seeing muscle cars, and love driving them even more.
Can't wait until the next Route 66 meet. It's always a blast to attend.
