I agreed to let my neighbor repair my 2012 mustang for the rear differential complete, he had me wait 5 weeks because he said he was researching and asked for 100.00 up front, I refused to wait, and to it to the dealer and they're charging price is 2250.00, the neighbor spoke of wanting to buy the car, I believe that's why he was taking his time so it depreciates, now he mad at me, and I don't care, is 2250 fair? or too much?
