Pulled the trigger on a local 2007 Denali yesterday. 1-owner, no accidents, 144K miles. Husband was a mechanic, and manic about this car. He put on 22" Verde rims w/Michelins, K&N cold air intake, Magnaflow ****, dark tint all around, etc. He died a few years ago, and the wife rarely drove it. ALL fluids look like they were changed yesterday. 40 oil psi on warm engine. Almost no wear on the interior, none of the rips/tears/wrinkles usually seen. It is not without flaws...mirrors do not fold in, neither front seat raises or lowers, button for lumbar does not work. I will likely find a few more of the common things. Headlights/tails were a hazy mess, which I took care of with a buffer and rubbing compound...maybe 30 seconds each. THRILLED TO HAVE IT! And, glad to have this site as a source.
