Exactly my experience as well. Got a few quotes to trade my 35 on a 37 and the difference was very similar regardless if it was MSRP or 10k mark up.I’ve been looking at several trucks, a couple of which were MSRP. My experience has been that dealerships offering MSRP are lowballing on trades and dealerships with reasonable markups are offering higher trade-in values. My OTD prices have all been with ~$2k of each other with trade-in values ranging from $51k on the low end to $62k on the high-end. KBB instant cash offer was $55,716.
