Depends on if he did all the work himself, or paid for it to be done. Either way, probably in the $20k range including cost of the car. At least, that's if it was all top notch suspension stuff. Could be bunk Chinese shit, but judging by the quality of work, I doubt it. That number could be off, because the motor was probably already in the car, so that's money saved on the swap.

Who knows.
