The 2012 Mecum Auctions train-of-fun stops in Des Moines, Iowa this weekend. The 2-day sale takes place July 20th – 21st at the Iowa State Fairgrounds. Velocity TV will have 12 hours of live coverage of the event. 500 hundred cars are expected and as we write this over 20 Corvettes are scheduled to cross the auction block.

The Des Moines sale offers 25 Corvettes from every generation except one. Sorry, C5 fans there’s nothing for you on the docket at this point in time, but we’re putting this preview together a little early so we suspect that more Corvettes will be added as we get closer to the auction date. Keep watch on Mecum’s website for more recent additions.

Here are 3 cars to keep an eye on in Des Moines.

Lot #S105 ?2010 Corvette ZR1 VIN 002:
The 2nd 2010 ZR1 was painted in Jet Stream Blue and delivered to GM’s Milford Proving grounds. It features the big dog, supercharged LS9 putting out 638hp. The black interior has been occupied for just 5,700 hundred miles since the car was new. We saw 2010 VIN 001 sell earlier this year at Barrett-Jackson Scottsdale for $203,500. We think this one could sell for half of that or less.

Lot #F181 ?1969 Corvette L88 Coupe Replica:
This car appears to be a quite well done (and honestly represented as a) L88 replica. Installed goodies include: aluminum heads, 4-speed transmission, F41 suspension, power brakes, leather interior, TI, and redline tires. This car is nearly identical to the real 1969 L88 that was a $385,000 no-sale last month at Bloomington Gold. Selling price on this one will be a fraction of that which is fantastic for all that L88 thunder which you can flog all you want without the fear of breaking a half-million dollar car.

Lot #F135 ? 1958 Hard Top Only Corvette Convertible:
A great looking 1958 that’s been body-on restored. The drivetrain consists of the 283ci/230hp engine, Powerglide, and a 3.36 rear end. Options include a Wonderbar radio, courtesy light, heater, and wide whitewalls. The exterior wears Signet Red paint accented by White coves which compliments the red and white interior.

Mecum’s Des Moines auction begins at 1pm central time Friday and at 10am Saturday. Velocity’s live coverage will air Friday 3-9pm CST and Saturday 1-7pm CST.
