Mike,
Make sure that you get the Manufacturers Statement of Origin (MSO)from Tom McBurnie at the time you make final payment for your Spyder. I bought my 550 "Phase III" Spyder package a year and a half ago. I drove from St. Louis to Thunder Ranch to pickup my purchase and was smart enough to get a signed receipt for it at that time, when I gave him a Cashier's Check for the balance owed. The MSO was supposed to be sent to me later. In spite of subsequent phone calls, emails and USPS mail requests and eventually even a complaint filed with the California Attorney General, I still do not have an MSO.
I will probably have to spend several hundred dollars for a title service to get a proper title for the Spyder.
Also, there's a thread somewhere else in the forum about the lack of any instructions or wiring diagrams for the "kit." Angela Lane was kind enough to provide me with a copy of the earlier assembly manual (which was a real time saver -- Thanks again , Angela), but I never did receive a copy of the one that was being "edited" when I picked-up the kit from TR early last year.
I know there are Spyder owners who are quite happy with their TR purchases, and I would be, too, if I had received those two items, as promised. Maybe McBurnie doesn't like guys with mustaches or ???
I've given-up trying to get those two items from TR, but I thought I'd give you a heads-up so you can avoid a similar fate.
Have fun with your project. It'll be a rewarding experience, albeit at times frustrating.
Jim
