Having just ordered a RT-S, I hope BRP hangs in during these bad economic times. One of the reasons I bought a Spyder (not the main reason, just one) was that my Wing is getting a little older and I was thinking of getting a 2012 and triking it. My dealer, guessing, said there will be a nice price increase on the Wing and the kits are going up as trikes become more popular.
This is my estimate, no facts. A new 2012 Wing, (lowest level) with the accessories I want, and am getting on the Spyder, (GPS, XM radio and CB), including tax, title and license, out the door, triked with the accessories I would want would run me about $38,000. This would include a rake kit. Yes, you can buy one cheaper on eBay, maybe....add +/- $3,000 if you get the high end Wing.
Today, if you want a CSC kit installed, in my area, it runs $14,000 to $15,000. This includes tax and some upgrades. This is my local pricing, you could do better in your area perhaps. My Spyder is much less than this. JMHO
