1996 Yukon GT

I am looking at buying a 96 Yukon GT. The veichle has been very well maintained. Oil chnage every 3000k, has 150,000 k on it. Interior is in mint shape.
What I am asking here is what are some things I should take a extra look at before buying this veichle? Are there any problem hotspots that should be looked into? Is this a good veichle overall?
I am currently in a 1999 Chevy Blazer and am just wanting a bit more space..and a nicer veichle.
Let's hear what you have to say, and thanks in advance.

I have a 97 Yukon GT, have the trans checked out, previous owner on mine had a factory crate trans installed so mine was ok. Check the top coolant line next to the thermostat top front of motor, it is connected with a small plastic cage and pushes in. They usually weep a bit after awhile...part is about $7 to replace the fitting. Check the oil cooler lines going to radiator from the remote oil filter, after about 100, 000 miles the high pressure hose expands the aluminum where they are crimped and they weep oil..also check the power steering lines for same problem. Some people have had problems with EVO sensor if yours exhibits any quirky steering problems. Also check differential seals for any leaks with those miles. Hope this helps a bit...
