American tuners are very good at making such things, very cool looking high performance concepts, but useless! Anyway, this Challenger SRT8 roadster by Group Five Limited will be on display at SEMA show in Vegas next week. Based on these renderings Challenger roadster also has modified front and rear bumper and customized bonnet, new tail lights and exhaust pipes, and it has only two seats. This might be only for showing off, but just imagine the pleasure of driving such ride! this is California luv!
