Thanks. Having roughly totalled up what I think everything on the car is worth second hand, it comes to nearer £8k so I'll have to seriously consider breaking it. Even if someone bought the car for £7k, they could probably make money on it if they broke it!
We'll see eh!
Build a quick website (loads of free options to do this) with pics, full spec, some commentary on the work done, and then stick a for sale page on to sell the parts. From here you can then list it everywhere, VAG forums (edition38, vagoc.co.uk etc), Pistonheads parts sale section, social media sites like facebook, twitter etc etc, and anywhere else you tend to 'hang about' online.
Nonetheless good luck with it mate whatever option suits!
