yeah, i've been there done that. know that exact feeling. and I'm just like you - I walked. lol. I'm willing to pay what it's worth, and maybe a little more if it's the exact bike / already has all the goodies on it (pipes, apes, etc). Last year I was at one dealer and they wanted 20k for a bone stock 2013 SG; I told them I'd give them 17.5k, which was right at market price at the time - actually about $500 over - and they didn't even budge off the price . Oh well. They proceeded to call me nearly every week trying to get me to come back in because they got some other bikes in etc. I was like "nah...you guys weren't willing to even consider a negotiation so there's no point. I know what they're worth, what they're going for, and what I'm willing to pay. So beyond that, we don't have much to talk about" lol. Then they throw out the "well come in, we'll make the numbers work". I said "dude...let me worry about the numbers/payment/term". I'm not terming out a bike for some reeruned term just so they can sell a bike for more than it's already worth.
yeah, ride that RK for another year or whatever, and let more and more used RGS hit the used market. Keep an eye on the used market in the meantime so you can watch how the prices inflate around this time of year, and significantly deflate the end of October each year. Plus, buying private party, saved me about $1500 in sales tax.
I like the newer RG fairings, how they're re-shaped. Not a fan at all of the older ones, but the newer ones look awesome.
