Welcome to the fold, Doogle.
As a VW nut myself I'm looking forward to seeing a 550 build and if Gary ever produces a 718 RSK body I'll be getting my cheque book out. Again. I hope it all comes together for you.
Gary's creations leave a lot more work for the builder than the more mainstream kit manufacturers, but you can't argue with his prices. I reckon my Sammio Spyder will cost me about 30% of what I was going to spend on a 356 Speedster replica, while I'd estimate that Gary's 550 will come in at around 50% to 60% of anything comparable.
Best of luck!
