what do I need to know when looking for a Tahoe

[BamaTahoefan]

I want to find a GMT800 to turn into a nice family ride and I am curious on what I need to be aware of with these trucks. I have been looking online and it seems to me that a truck with about 120k-150k miles will run about $9-$10k. Does this seem about right? What I want is a rust free (not too hard in Alabama) 4x4, leather interior, third row seat, reasonable mileage. I figure that as long as the body is good and the interior is not trashed beyond new carpets and seat covers that I can rebuild the engine and transmission for a reasonable price and end up with a great vehicle to last for quite awhile. Now I ask for y'all to share anything I might need to know as I start searching for a project.

Thanks
