Other than the colour changes your getting a few different bits.
Different rear cvd's, battery thumb screws, carbide diff balls, big bores etc etc.. there are some other bits that i cant remember.. i have the exploded diagram of the new RB5 and FS2 so can see easily
So very easy to have a similar car if your upgrading it will just be a different colour! blue rather than gunmetal
Ok the price of the car might be high, but have to say it will be the most complete car out of the box... no reall hop ups needed!
