I agree with Ren and Ed on this one. No matter how long you have the property, that does not make it yours. You may have bought a car with the wheels on it, but YOU KNEW that you were supposed to return the wheels to Allen. The wheels were not yours to sell/trade, and you just sold stolen property. Allen has every right to be upset, and his "threat" of legal action is COMPLETELY acceptable at this point. It wasnt stock supra wheels or some cheap discount tire closeout special, these are very expensive wheels.

Good luck Allen. Sounds like you are going to need it.
