I've had my 2012 dodge charger since april of 2013 got it for 30000$ and it has an r/t logos on it an its a 5.7liter v8, well at least thats what the engine says. My car manual is over several different charger types and i dont know which type i have, how do i figure this out like is it an r/t plus, awd, rwd, r/t race and track? Please help
