New guy here... Always been a FORD (2013 Raptor as my daily) guy but the wife wants a new grocery car and kid hauler and she likes the looks of the Yukons. We're looking at a used 2015 Yukon SLT with 40,000 miles for $35k. I wasn't impressed the motor/tranny in the Tahoes/Yukons...they lack some "get-up-and-go" IMO as compared to the Expeditions. But I do prefer the looks over the Expy. Any known issues on the 2015 Yukons that I should be aware of?
