I think a retractable hardtop convertible would be an extremely expensive proposition (come on - it's a DODGE, not a BMW...). As long as it doesn't look like Conestoga wagon with the top up, I think a soft top will do just fine - especially considering its target market.

While I would personally never buy a ragtop Challenger, I still think Dodge would be foolish not to make one. Ford has a Mustang convertible, and Chevy is no doubt gonna offer a ragtop Camaro... it's only fitting that Dodge offer a ragtop Challenger. God knows they need a good looking convertible since Chrysler mortifyingly uglified the Sebring last year. [:'(]
