Well not really mate, you see I understand that somethings only worth what people are going to pay for it. However I also know that some things on Ebay, people want for nothing. Cars are one such thing, it's been over saturated and no one will pay anything for anything unfortunataly!
NEVER sell on Ebay, unless you want a quick sale (Cars this is)
I also said that more details are necessary, these could drastically change the price that the motor is worth.
A MINT 16v with electric windows, mirrors and BBS, and FULL VW service would be worth at least £1.5k, only an idiot (or desperate folk) would let it go for £500. You can't really guarantee getting a MINT 8v for under a grand, never mind a 16v.
But it all depends on the cra ya see?
