Really the only thing I would be concerned with is was it garage kept? If it wasn’t garage kept, that paint is probably ruined from baking in the sun. Otherwise, with only 42k miles there should be next to nothing wrong with it and I’d pay all the money.
I REALLY wish I had waited and paid more for a lower mileage truck. There’s currently a private seller Escalade ESV Platinum near me with only 85k miles that looks like it was garage kept for $30k. I’ve easily spent more than $10k on mine fixing all the issues from the paint to the beat interior.
