just in case..
I am cross posting this, and hope everyone understands why.. Lets just say it sounds like you are looking.
https://offerup.com/item/detail/608207359/01 GMC Yukon Denali (XL?) (not affiliated) $3K obo.
01 Denali black on gray with only 138K miles, just popped up yesterday, 3K OBO. Interior and Paint/body look good from the few pictures I can see. I'm pretty sure that's an XL (looking at the rear door looking like it comes all the way down) which is about the only reason I'm not interested in it. If someone is looking for one of these, I have been searching from Socal to Vegas/Utah out to dallas/san Antonio. BASED OFF THE FEW PICTURES: this is one of the cleanest, lowest price, and lowest mileage ones I have seen.
From what I have seen around the rest of the country, I could probably buy this, drive heading some kind of North with a for sale sign in the window and double my money.
