Holy crap! Did I ever avoid being fleeced a few weeks ago! I was at my dealer; getting my R shocks replaced with the Rev 1s. Got tired of watching flip it shows on HGTV in the service waiting area. Wandered over to sales; saw the salesman I'd bought my '12 SE Sport, and '13 ST from; started kicking the game around. Eventually he works around to trying to sell me a '21 California Special Mustang GT Convertible (on their lot). I'm not interested in the Stang at all, but figured what the heck, and ask what they'll give me for my RS2 on trade. So the dealer's used car assessor takes the RS for a Spin; comes back and says $21,000.00. Yea, OK. Have a good day guys; I'll ring you if I get serious.
So, after reading all the above; I calculated my RS at KBB.
Trade: $34,869-$38,138; ave: $36,504.00!!! WTFlip??!! KBB aver is 57% more than the Stealer was offering! 🖕 Real glad I don't like convertibles!

In fairness I think KBB is a bit optimistic on their trade in value too, but damn! That's a BIG gap.
