Consider using a more modern platform. You can score an A3 GTI for a couple of grand, and from there out everything else pretty much costs the same. The reason I say that is because the A3's are beginning to show that they can do the job well, and the modern fuel systems and electronics are more reliable and easier to manage IMO. Seriously plunk down a little more cash for a newer model, beyond that it's almost all the same parts, cage, suspension, diff, etc.
The truth is, I just like them and want to see more out there! :D
