My Lady had a convertible Rabbit. She took my truck to work one day and I had to run errands in that thing. I felt... less than manly. [

Personally, I think the Challenger is fine as is. I like convertible cars, but I just don't think this one is going to look right as a convertible. (And based on that Photoshop, I think I'm right.) The PT Cruiser convertible is horrific, as is the Mini convertible. If the car wasn't specifically designed as a convertible, I say leave it alone.
No ragtop. No T-top. No sunroof. No moonroof (whatever that is). Just leave it as is. And make it NOW.
k.thx.bye.
