9. Suspension - Tires
Another quick thing to check is the suspension and tires. Pushing down on each corner of the car should give the mechanic plenty of information about the state the shocks are in. If it bounces once, and returns to its normal position, then it should be fine, otherwise the shocks might be shot. A test drive will help cement any suspicions about the suspension.
Tires are another important factor. Ensure they’re not leaking air, and that the spare is in good shape too. Mechanics will check them for uneven wear which will hint at alignment problems.
