Welcome. I traded my RT for my R-18C. I've had a couple of 1200 RTs and I have nothing, but good to say about them (whizzer brakes equipped 06 and LC 16 with approximately 100,000 combined miles), but they are so dissimilar from the R18 that you need to ride them back to back if possible and for some reasonable miles/hours. You should bring your own vaseline as the biggest depreciation is immediately after you buy it and then try to quickly trade. You and the dealer can shuffle the numbers to make you feel better, but the bottom line is your's is used and some shops still have new and or new demo models with huge interest rate and rebate incentives that your's won't have to entice a buyer. That said, I've done similar a couple times over many years with my limited self control

and I just accepted it and didn't look back, but make sure it's for good reason as it really is throwing away perfectly good money. I try to behave like in the old saying of "measure twice and cut once", but it's hard with so many great bikes being offered by all the OEMs nowadays.
