yup thats 2!
the 1 with the back up sensor is the gti,sensor came with it when we bought it last april.
the gti was the one with amg sides,i took off all the goodies and its up for sale as a stock gti.
it took 3 cars to build both amgs
still need an amg spoiler for the blue car
the black one needs to be painted soon,i dont like the 2 tone and flat black spoiler.
got to get them together soon.
