Before you buy: check and equip

Check the history

Before paying, check the administrative status (lien, objection, declared claims) and the mileage recorded at the roadworthiness test.

Read fault codes

An OBD scanner plugged in under the steering wheel shows stored fault codes, even with warning lights off: useful during the test drive.

Parts and maintenance

Compare prices of parts for the Mercedes-Benz (timing, brakes, filters) to estimate the repairs to plan for.

Insure the car

Insurance prices vary widely from one model to another: get a quote before signing.
