Possible New Vehicle 2005 Yukon XL Denali

[kablooie]

seems like a steal, not bad of a price either. things to watch for, castec heads, air ride suspension going bad, fueling problem.

may be worth the visit to look at in person and hear it run/inspect it.

what is there specific to look at in regards to the heads? compression testing?? anything to look for re suspension, etc. tell tale signs or things to point to a mechanic that should be addressed/replaced/repaired?

I just got my 06 deniali xl from carmax and have 3 more weeks on their warranty.
TIA

Bladder on rear shocks are dry rotted, appear to have fluid leaking from them. With the key on during first start, you should hear the compressor air the shocks up, if not,it's blown or you have a bad unit or bad shocks. Service air ride message in the doc as well. Milky oil is a a telltale sign of coolant making its way into the oil via either a cracked/warped head or bad head gasket. Difficulty fueling vehicle ( excessive handle squeezes and fuel pumps pennies or dollars at a time) are an indication for the failed evap system.. Tins of threads on all these issues on this forum

So when I turn my key on, I don't hear any noise @ all no air compressor noise. Sign that it's bad potentially?
