I have the same scars - There were three dealers within 70 miles, when I bought my RS, then the best one went out of business, and the closest one couldn't sell me a free hot dog. Over the years the dealer that's roughly 70 miles away became a first class act, with a terrific service department, and top flight sales team. They know and LIKE Can Am products. Finding and supporting a good dealer is the most important part of Spyder ownership - IMHO.
For me, even with a terrific dealer, 140 miles is a joke for servicing a toy, and, at my age, wrenching on a Spyder is more effort than I want to expend.
Before anyone buys a Spyder, I would recommend spending a couple of Saturdays (or whatever days off you have) at your local dealers, talking to the TECHS. Make sure they can meet your needs. A good trusted dealer can provide a reliable pre-trip service, that will give you confidence your Spyder will get you there and home.
If you are going on a long trip, check with the locals on this Forum, and find a GREAT dealer - If you arrive and have any concerns or questions, have them do a quick once over, before you head home. The Spyder IS a complex toy, and need to be treated as such.
Just some thoughts...
