We can never give you a value for an individual car, but we can offer a bit of guidance. You don't say whether your Scirocco is a Mk1 or a Mk2, but as it was registered in 1981 it's probably a Mk1. In which case, we'd expect to see a first class example on a dealer's forecourt for about £7000 or in the classifieds for £5000. At the other end of the spectrum, you could pick up a project with a short MoT but definitely in need of TLC for about £1500. The best thing to do, is try to find a car in a similar condition to yours and price it accordingly. Scirocco prices have been rising in recent years.
