Mecum’s September auction in Dallas provided some fodder for commentary. I’ll concentrate on the at least fairly stock 1980s cars (and a few trucks) that sold (remember that Mecum auctions are not no reserve auctions—a grand prix white 1982 Porsche 930 Turbo coupe with can-can red leather seats and 17,000 miles was a no sale bid up to $77,500) and add some of my opinions. Eighties vehicles were about 7% of the 450 vehicle lots sold in this auction.

- 1984 blue Mercedes-Benz 380SL convertible with tan seats, a 155 bhp 3.8 liter/234 cubic inch V8 with Bosch Jetronic fuel injection, and an automatic—$7,000 hammer price.

Thursday, September 7th:
- 1980 white Chevrolet Camaro Z28 coupe with a blue interior, an LM1 190 bhp 5.7 liter/350 cubic inch V8 with a Rochester four-barrel carburetor, and an automatic. At $12,500, the first vehicle in this auction to meet my criteria for serious 1980s collectability of original cars or trucks: selling for equal to or above its original base list price. I’ll mark these vehicles in bold green.

- 1981 red Chevrolet Corvette coupe with medium red leather seats, an L81 190 bhp 5.7 liter/350 cubic inch V8 with a Rochester Quadrajet four-barrel carburetor, and a four-speed manual—$12,500. If you like 1981 Corvettes, this seems to have been your auction.
