My wife just bought me a 2010 Challenger R/T for my retirement. Well, I guess she is a keeper . I got the $2000 mopar bucks from the purchase and need to spend the money within 30 days from purchase. What are the better parts to consider? I would like to keep the mods simple, not looking to peel the motor apart. I got the hood cylinders, front end brace and car cover. Any other suggestions?
