I know I already asked this under the supporting vendors area but it looked like no one saw so here it is again:
How much are your 6 packages for the challenger going to run for people who already have challengers and arent looking to buy a speedfactory car but just the package for the car. Also will we be able to opt out of certain things included in the package to bring the price down such as some visual things? Thanks.
