$21,280
Considering I sold my 9 yr old 325xiT with around 104k miles (and leatherette which I think af's brother's is missing ) for around $6 TO $6.5K (not quite sure of the exact number) I would say the price is super high.
The unfortunate reality is slushies suck, curb rash bites, and dimples are cute on people's cheeks, but not on their cars, all knows to not add to the price of a used car unless you find that buyer who is in the 1% range who just happens to be looking for this exact car.
If anything they diminish the value.
