JPV, sorry you're having problems and I agree that BRP might be in trouble if one of the Japanese manufacturers should begin making a reverse trike. But I think the trouble would stem from the reputations of the big 4 Japanese manufacturers rather than any real difference in quality. The Japanese build some excellent products but My 2010 RT has given me 6500 trouble free miles, so far, so I can't complain about the quality. The Japanese brands also have a much larger dealer network and that competition may cause their dealers to do a better job on customer service. It seems like in some cities there's a Honda dealer on every corner and, unfortunately, that's just not the case with Spyder dealers.
As far as a dealer keeping my RT a week before they start work on it - that's just not gonna happen. My dealer has been excellent but I've only had the RT in for service work and I've always called beforehand and made an apointment which they set up. If I have to take it in for repair, whatever the problem, and they can't get to it the day I bring it in, I'll simply take it home and bring it back when they can get to it. I'm not saying they might not keep it more than a day. The length of time they keep it depends on the work it needs and how long it takes to get parts. But I am saying that I won't leave it at the shop if they can't begin working on it the day I bring it in.
