Am I pricing my car too high? (not shameless plug)

[WhoreLex]

I'm trying to sell my Ibiza now that the misses has passed her test, its a cat d in fair condition.

I've gone with the idea that a cat d should be 60 to 70 % cheaper than a non damaged car, so by my esitmation thats £2700 ish (29k miles), but my auction just finished on ebay and it only went to £1500.

So PH hive mind, is my car too expensive?
