The good one: 1957 Chevy Bel-Air 2-Dr Hardtop. In some ways, sort of a dirt-road special: Interior had been recovered in red & black vinyl, had been converted from Powerglide to 3-sp on the floor(with world's oldest Hurst shifter!), 283 ci V8(with PowerPak heads), primitive-looking Carter WCFB 4-bbl carb, oil bath air cleaner. The generator(*Not* alternator!) had a splined shaft coming out the rear, the power steering pump fit onto that & bolted to rear of generator. It had a 4-Track(yes, a 4-track!) tape player in it, few tapes found under the seat.(Dean Martin, Supremes, & an Elvis that was worn out) Prices weren't insane back then- IIRC, seller asked $600 & I bought it for $475. Drove it for about 2 1/2 yrs, spent almost nothing on it(bought a newer better Hurst flat-bar shifter for $8. Bought another 3-sp trans at junkyard for $10. Ran Sears Re-Cap tires on it. I did put a semi-decent 8-track in it.) Sat down with local parts guy to see what it would take to make a nice car out of it(add 327 or 350 V8, go to ATx or 4-sp, interior, fix fender, repaint, add air cond, etc. Woulda taken a min of $1200, more like $1500- and then I coulda turned around & sold it- if I was *Very* lucky- for *Maybe* $1200. That just didn't make sense even to a 19-yr old kid(who still secretly lusted after a 66-67 GTO!) Sold it with a cracked block & pushed-in front fender for $275. I later heard the Guy who bought it got it all going, drove it just a few times & then went way too fast & was terribly injured. Car was destroyed of course.
It wasn't until a few years after I sold it that prices on 55-57 Chevys began to get ridiculous.
