I just want the rims
Seeing as the rims would cost $30 and the car at the cheapest for a MS $20 and the dual bats, paint, springs and labor another $20-$30 is reasonable. I'ld say $75 for the car with that setup but good luck finding people to buy.
Edit-See what I mean $40-50 maybe you could use a clone. I also forgot you said that was a booster up top, that ups it.
