I recently saw two interesting, but wildly different, cars on the Hemmings online classifieds for the same price. The first, a 1957 Ford Thunderbird, proves that blackwall tires instantly testosterone-ify any vehicle from the 1950s. Normally, I?m not that much of a fan of first-gen T-birds; leave ?em to the lost-in-the-?50s, sock-hop-and-James-Dean types. But the blackwall tires, the body color wheels and the McCulloch blower underhood all have me reconsidering early Birds. The second, a chopped, slammed and apparently stretched 1955 Porsche 356A, proves that, well, it doesn?t really prove much. The ad doesn?t state whether it?s a repro body or not; either way, some Porsche purist will have a heart attack at the sight of it.
