How close is KBB for REAL Porsche Value?

[dghii]

All I can tell you is I find KBB to be a little high for Boxsters. Take your same car and get the numbers from Edmunds or NADA. They results will all be differnet. Really just have to look at what the asking prices are for cars in your area.

You might want to check completed autions on ebay as another reference, looking at the auctions that actually closed, or cars that received lots of bids. Its not perfect but does give you another data point.
