Check KBB and Truecar. My RST is rated between 38-41k. I flirted with the idea of getting something new during the incentives the past few months and had offers of 38k from multiple dealiars, but they wouldn't budge on theirs. I suspected I could get it closer to the 40k had I pushed. Being a Trail Boss, I suspect they'll be a bit stronger. KBB is at least a good starting point before talking to dealiars.
