I went and test drove both yesterday. Here's what didn't make sense.. I ended up driving an slt and a lt as the dealer had both. I'm not sure if the Yukon had been wrecked but the car felt off. AC would fluctuate and the seats were not comfy, felt like extremely worn. The Tahoe felt more solid, more responsive, and much more padded seats. They both had 40k miles. Interior in the Tahoe smelled like wet feet so I walked from both. Is this expected between the two? I would have assumed the Yukon would have been nicer
