I'm going to wait a few years possibly so I can rank up in the Army and know that I can live stable to buy a charger I want to buy a 2012 RT but I know there's like 3 or 4 different RT's so I want the regular RT but I'm not sure if it will take away performance what is the difference between them?also after I buy one I plan on putting an srt8 grill on the front since they look more aggressive and I'm might go for a matte gray paint job and black rims, so any suggestions or thoughts and which RT is best?
