I don't think there is any real way to tell except to look at the average depreciation of other VW's in the past. I was recently rear ended and am working with an adjuster on a diminished value claim to recover loss of value, and trust me, it is not easy on this car.. None of the insurance companies have it in their databases, they had to do a repair quote using the costs of parts on a 05 GTI. So, you wont find a resale value on this car until probably next year. If you want to look at the trade in value, go to a dealership or carmax and get a quote, but that obviously not be the way to sell..
