Well, I actually got my '86 corolla back, so that doesn't count. Bought it for $900 and drove it year round for 4 years. Best buy I ever made.
I do miss my '98 Trans Am. An entirely different animal compared to my current cars. Got laid off when I was still paying for it and it got repo'd.
I've loved all my cars, even the '81 Regal with a broken bench seat, busted motor mount, leaked oil like a sieve, and was painted with house paint complete with brush strokes. But only a couple have had a storong sentimental attachment. My current cars (STI, WRX, Corolla) all do, and I'd hate to part with any of them.
