460le how much$$$$$

A buddy wants to buy my a4 but it has been rebulit about 2 years and I have felt the gears slip a few times however he know this but he want to buy it i dont want to rip him off, but at the same time i dont want to get ripped either any suggestions. Also I really want to sell it for the t56 swap.

If the "gears" are slipping, you might want to just go ahead and throw the thing in the dumpster.

Seriously....you may wanna post this in another forum not dedicated to the 5th gen/future vehicles...
