The Mercedes-Benz C400 is a luxurious and powerful sedan that offers a refined driving experience, but like any pre-owned vehicle, it’s essential to do your homework before making a purchase. Start by checking the vehicle’s service history—regular maintenance at authorized dealerships is a good sign of responsible ownership. Pay close attention to the mileage, and look for signs of wear and tear, especially on the brakes, suspension, and tires. A pre-purchase inspection by a certified mechanic is strongly recommended to spot potential issues with the engine, transmission, or electronics, which can be costly to repair on a high-end German car.

Additionally, verify that the vehicle’s VIN (Vehicle Identification Number) matches on all documents and inspect for any accident history through a Carfax or similar report. It’s also important to test all interior features such as the infotainment system, sunroof, climate control, and safety systems like blind-spot monitoring or lane assist. Given that the C400 comes with a twin-turbo V6, ensure that the turbochargers are functioning properly and listen for any unusual engine noises during your test drive. A well-maintained C400 can be a rewarding investment, blending performance, comfort, and style—just make sure you buy smart.
