can i ask a price to buy car question...1999 only 40K mileage one owner ask 3500

Look on www.kbb.com, its free and is pretty much industry standard for prices of cars. Look on Craigslist, Autoshop, and dealers in your area to see what a comparable car goes for. Have a pre-purchase inspection done by a garage knowledgeable in VW products, it will be money well spent, hat they find may divert you from buying a "bad car" and or what they find (lack of maintenance or repairs needed) can be used to negotiate price.
