The Hertz Shelby GT-H hit the auction scene with a bang back in 2007, as the first black and gold drop-top sold at Barrett Jackson for a hefty $250k . In the past year, the powerful pony cars have had to endure some wear and tear from reckless renters, and what’s likely to be a much lower price of ownership. Between 75 and 100 Shelby GT-H Convertibles are scheduled to hit the block at Kruse’s 17th Annual Auburn Spring Motorfair from May 29 to June 1, 2008.

The special edition Mustangs will still likely cost a large premium over the average Mustang leaving rental duty, both because of its Shelby origins and limited production run of 500 vehicles. But in return you get a speedy convertible with truly unique looks. If you would like a Shelby GT-H Mustang, but have no plans or desire to head over to Indiana, you can even bid for the weekend racer of your dreams right from the Kruse website. Hit the jump to read the Auburn Spring Motorfair press release.

While Cadillac busies itself with a 2-door version of the new CTS sedan, the folks over at Coach Builders, Ltd have been busy taking their tops off. The boulevardier CTS gets an insulated, hydraulically-powered roof fitted with a heated glass rear window and cloth headliner. The top also comes in several colors. Judging by this pic, it also looks like a fair bit of work has gone into making the car look good with the top down. No word on what happens to trunk space, however.

It’ll cost you more than a few quarters — $19,000 gets the job done in eight weeks — but that’s the price of exclusivity, right? It’s also employs a manual release, but these things happen when you’re a style pioneer. We’d like to see pics of the car with the top up, because we wonder if this could be the first cloth-topped Caddy truly fit for the younger set.
