Ive got one in my garage at the moment. I bought it of a member of our local group as he'd lost interest in in. I'm in the process of stripping it and rebuilding it to get it better prepared for trackdays. Ive got the dash out to get it flocked and luckily havent found any bodges so far with the wiring etc etc. Cage is next.

Like has been said above, build them right and they should be as good as gold. Mine will be having a c20let fitted in due course.

Buy one done and save yourself a load of time and money. Just be prepared to give it a good going over to satisfy yourself its been done right.
