Why Use Genuine Mercedes-Benz Parts

Keep it Genuine

You drive a Mercedes-Benz because you expect the best. When your vehicle requires maintenance or repair, be sure to accept nothing less than the dependable fit and quality of Genuine Mercedes-Benz parts. Keeping it genuine means protecting your investment and continuing to experience all the performance, style, comfort, and safety you expect from your Mercedes-Benz.

Mercedes-Benz Oil, Air, and Fuel Filters
They're not just filters. They're essential components that drive the performance and longevity of your vehicle by preventing harmful contaminants from damaging your engine. The proper care and maintenance of your vehicle must include the use of nothing but Genuine Mercedes-Benz oil, air, and fuel filters.

Here's why ?
Our oil, air, and fuel filters are not imitations. They are the true replacement parts that were designed to the exact specifications of your vehicle.

Mercedes-Benz Windshield Wipers

Maintaining proper visibility while driving your vehicle is essential at all times. Did you know that Mercedes-Benz wipers are specifically designed with curvature and pressure points that perfectly conform to your windshield? Wipers of lesser quality may not have this unique design feature and may be subject to premature wear or failure.

Genuine Mercedes-Benz windshield wipers are developed, manufactured, and tested in accordance with the strictest quality standards. They consist of both natural and synthetic rubbers, which provide the best possible, long lasting elasticity. There is no better choice available where your and your passengers' safety is concerned.

Collision Parts and Service

If your vehicle has been in an accident, you may be anticipating the stress and hassle of having to deal with insurance companies and body shops. Mercedes-Benz of St. Charles will help guide you through the process of getting your vehicle back to its pre-accident condition. Mercedes-Benz of St. Charles has the solution in the Certified Collision Program.

The Mercedes-Benz Certified Collision Program was developed to set the highest standards for repair work, training, equipment and customer service. You can maintain the value, fit, finish and safety of your vehicle by having it repaired at a certified collision center. You expect exemplary service, genuine parts, and outstanding craftsmanship in the repair of your vehicle; only a Mercedes-Benz certified collision center can consistently provide this.

Mercedes-Benz Replacement Glass

Automotive glass is an important part of your vehicle's structural integrity. Using Mercedes-Benz Star Labeled replacement glass, built with advanced glass technology, assures that the safety and quality designed into your vehicle is maintained.

Every Mercedes-Benz windshield and back glass is engineered to provide these key benefits: proper fitment, visual clarity, windshield wiper performance, and the overall integrity of your vehicle.

Windshield tolerances are an important part of any replacement glass and Mercedes-Benz glass is manufactured to maximum tolerances based off of the original design. However, aftermarket glass can be reverse engineered.

Mercedes-Benz Heating and Air Conditioning (HVAC)

Your Mercedes-Benz is equipped with a highly sophisticated heating, ventilation, and air conditioning system (HVAC) that maintains a clean and comfortable atmosphere within the vehicle. A well-functioning HVAC system will not only optimize climate control and defroster operation, it well help maintain the MPG rating over the life of the vehicle. Regular checks and preventative maintenance (e.g., cabin filter, A/C compressor) performed with genuine Mercedes-Benz parts will keep the system doing its job and help prevent potential costly repairs.  Who in the St. Charles, O'Fallon, and St. Louis area can tolerate a broken AC during the hot Missouri summers?

Mercedes-Benz Brakes

Stop! Never underestimate the most critical safety feature of your Mercedes-Benz. The Mercedes-Benz braking system was designed to the unique specifications of your vehicle, and features brake pads and rotors made from precisely engineered metal compounds designed to safely transfer heat and provide superior mechanical strength. This ensures the system's ability to bring you and two tons of accelerated machinery to a safe and sure stop, time and time again, under both normal and extreme conditions.

Mercedes-Benz Exterior Lighting

The lasting value of Genuine Mercedes-Benz headlamps and taillights has always been crystal clear. If road debris or an accident causes damage to any of your lights, replacement with an after-market unit may seem acceptable. However, keep in mind the exterior lighting on your vehicle does much more than just illuminate the road. Here are reasons why you should always insist on Genuine Mercedes-Benz replacement units.

  •     Vibration resistant construction that eliminates flickering on bumpy roads
  •     Precision fit that provides ease of installation and minimizes wind noise
  •     Ventilation to minimize inner lens misting and preserve clarity
