what is the greatest achievements you did on your car.

I HID MINE FOR TWO YEARS BEFORE THE WIFE FOUND IT! That count?

I bought my car trailer at a car show (yes, my wife was there and knew about it). A friend of mine was going to go buy it, but I beat him to it. At the end of the show he asked me if it was going home empty. It was until he asked if I would deliver a Challenger to his house. He told me to tell his wife it was a customer car...not sure what he told her later...
