I'm constantly skimming Ebay Motors for Porsches and I always sort the results by mileage first, scroll down until I'm in the $$$ area that I'm looking to spend. The prices for high end cars are always marked up on Ebay (and reflected in the 'Buy it Now' price) but I look at the bids. If there are no bids obviously the car is priced above the market. The closer the auction is to its end the higher the bids if the car is priced realistically. But keep in mind that internet sales for cars tend to be lower (on average) than local sales. Particularly in areas where supply is low.

and as far as mileage, if its not CPO'd, I need a screaming deal to even consider a car with mileage north of 50K. Too many garage queens out there looking for homes. I'm sometimes amazed at how little the price difference for a car with 20K and one with double the mileage.
