Buying From Mercedes-Benz of St. Louis

Mercedes-Benz of St. Louis sells new Mercedes-Benz vehicles and usually takes trade ins, so its used lot is a mix of brands. A certified car from the brand program comes with a factory backed warranty. A used car that is not certified is sold on the same terms as any other used car, so read the window sticker. How certified cars work.

Luxury cars cost the most to get wrong. One deferred service item can cost more than an inspection many times over.

Whatever the grade, the grade is about the dealer. The car is its own question. Ask the dealer if an independent inspection is allowed before you sign. A good lot says yes.

Common Questions

Is Mercedes-Benz of St. Louis a good dealer?
Mercedes-Benz of St. Louis earns an A in the PPI Auto Buyer's Guide. Past buyers are close to unanimous. Few complaints across a long record. The grade reads 1,535 public reviews averaging 4.7 stars, with 6.6 percent at one or two stars. It rates past buyers' experience with the dealer, not any single car.
Can I get a car at Mercedes-Benz of St. Louis inspected before I buy?
Yes. PPI Auto sends an inspector to the car on the lot in St. Louis. You do not have to be there. The inspection covers 122 points, a full OBD-II scan with readiness monitors, a road test and photos of anything found, and the report comes the same day. Ask the dealer to hold the car while it is checked.
How is the grade worked out?
It needs 20 or more public reviews. The star average is pulled toward the national average by 25 average reviews so a short record cannot jump the line, and the share of one and two star reviews sets a ceiling. The full method is on our grading page.
