Petrol
Turn the steering wheel fully to the lock in both directions while stationary to check for any 'click-clack' noises from the column or steering rack.
Accelerate firmly in second or third gear and observe the gear shifter; if it jerks excessively, it is worth inspecting the engine and transmission mounts for signs of wear.
Operate the climate control through all fan speeds and temperature zones; check if the digital display flickers, as these units can occasionally develop connectivity issues in cars of this age.
Inspect the headlight motor operation; ensure both pods rise and retract smoothly without stuttering, as the gears inside can wear down over time.
Usually the time to evaluate the condition of the suspension bushings and shocks for optimal handling.
A common point to review the fuel pump performance and verify that the fuel filter has been refreshed.
Typically recommended to inspect the accessory drive belts and idler pulleys to ensure everything runs quietly.
Check that the oil pressure remains steady at cruising speeds to ensure the LS1 heart is pumping as it should.
Inspect the coolant reservoir for any signs of sediment; a clean system helps keep the engine running at ideal temperatures.
Test all exterior lighting and signals, as aging wiring contacts can occasionally develop high resistance.
Verify that the battery terminals are free from corrosion to ensure consistent starting performance.
Ensure the soft-top mechanism (if convertible) latches firmly and the seals look pliable to keep the cabin dry.
Estimated repair costs if issues arise
In cars of this age, it is common to consider the condition of the rubber in the harmonic balancer. If you notice a wobble at the front of the engine, you might eventually need to budget for a replacement.
To maintain a smooth driveline, keep an eye on any unusual vibrations. If the couplers show signs of wear, this is a labour-intensive job involving the removal of the rear subframe.
These units can occasionally become sluggish as they age. If the windows struggle to close, you might eventually need to budget for a motor or regulator replacement.
