Mod Squad Challenger just auctioned, only 2 were made in 1972 that were convertible, both were for the tv show

see this gallery of the restoration of one at http://www.streetfire.net/photo/mod-squad-challenger-tv-car_1304342.htm or see a feature in Mopar Muscle Sept 1987
One just sold at Mecum at Monterey auction for 48500

The 1971 Dodge Challenger Convertible offered was one of the two or three cars used for on-screen work during the 1972 Mod Squad season. Since Chrysler discontinued Challenger Convertible production after 1971, this car was updated with 1972-specific front and rear components, creating an interesting hybrid. Highly optioned with an automatic transmission, bucket seats and a console, it was also used as a PR/show car in period. Today, it displays an exterior refinish dating back 10 years

Mercedes-Benz CL-Class AMG Convertible Conversion

With every passing year, there seems to be more convertibles on the market. But if you live in a sunny clime like California's, enough sunshine is never enough. That's where convertible chop-shops like Newport Convertible Engineering step in. The folks at NCE will take just about any automobile and turn it into a custom cabrio to a buyer's specifications. The company's portfolio includes recent conversions of a Dodge Challenger, Toyota Prius, Cadillac CTS, Hummer H2, Toyota FJ Cruiser, and this Mercedes-Benz CL AMG. Unfortunately, from the photos seen here, the soft top doesn't seem to collapse quite flush with the rear deck, leaving something to be desired in terms of aesthetics – to say nothing of rearward visibility. Here's hoping there's a snug-fitting cover lurking in whatever trunkspace remains.

Nissan GT-R R35 Convertible Concept

Check out these interesting and unofficial Nissan GT-R R35 Convertible Renderings which recently showed up on AutoJunk.nl and DeviantArt.com. With all the hype surrounding the recently released Nissan GT-R and the sold out level of demand it has endured, it’s hard to fathom that Nissan would contemplate a convertible version.

I know most purist or GT-R cult leaders would drop their jaws if a convertible version would ever make its way out of momma Godzilla’s womb. Either way what do you think of the renderings? I think they are pretty slick, however I wouldn’t be caught dead owning or driving one (unless it was the GF’s).
