Shift the vehicle into 4WD mode while at a low speed to ensure the transfer case engages smoothly without clunking or hesitation.
Monitor the instrument cluster gauges while idling; ensure the oil pressure gauge remains steady, as these units can sometimes show sensor drift on older clusters.
Listen carefully for a 'tick' from the engine bay when cold starting, as it's common to consider inspecting the exhaust manifold bolts for potential snapping or gasket leaks.
Operate the window switches and climate control buttons multiple times, as the interior plastics and electrical contacts may show their age in this generation.
Usually the time to evaluate the condition of the suspension bushings and shocks.

A common point to check the cooling system, including hoses and the radiator, to ensure longevity.
Check for a consistent service history, especially regular oil changes, which the Vortec engine thrives on.
Inspect the coolant reservoir for any signs of sediment or oil contamination.
Ensure all steering components are tight and responsive during your test drive.
Verify that the power seats and memory functions are fully operational.

Estimated repair costs if issues arise

Some trims feature air suspension which can eventually lose its effectiveness. Depending on the car's history, you might eventually need to budget for replacing bags or converting to standard coils.
Preventative maintenance on the water pump and radiator helps keep the V8 running at optimal temperatures. It is a smart move to set aside funds for this as part of your Future Budget Planning.
