The Rigorous 150+ Point Inspection

From the proper operation of the engine and brakes to the condition of the sun shade and map lights, you can be sure that each Optimum Vehicle has been meticulously inspected by licensed mechanics before it's offered for sale. During the inspection process, each vehicle must pass a check of a minimum of 150 different points. This ensures the vehicle is in excellent condition - inside and out. On some vehicles, up to 180 different points are inspected. Plus, regular maintenance is performed and faulty components are repaired or replaced.

A GM trained technician performs the following 150-plus point inspection on every Optimum Used Vehicle:
