When it comes to Golfs, high-performance models such as the GTi tend to command the strongest prices. However, there is a solid market for unmolested examples in good condition. A really good non-GTi example would be about £2500 on a dealer's forecourt or about £1900 in the classifieds. One that's a bit scruffy and in need of some TLC would be anywhere around £1000, while a non-runner or a project would be £750. Try to find a similar car to yours and price it accordingly - but be careful, the market can be skewed by people asking more because it's their car's been modified.
