I'm just about ready to order my MkIII kit and I have a question. The kit is advertised as having everything required except for the parts from a donor. I know there are tons of options available, of which I will be purchasing a few. What I would like to know is if you have a complete donor car and the MkIII kit, do you actually have EVERYTHING required to build the car. I'm just a little worried that I'm going to order a kit and find out that I was supposed to order some other expensive items in order to complete my build(I'm a skeptic, I know). I realize back orders are possible and that's not what's concerning me. In your experiences, are the kits complete in what you actually need, not including what you want as upgrades or options. Thanks for your help.
