At Auffenberg Mazda We Look Forward to Serving You Long After the Sale is Done

With any purchase of a new or used vehicle, you're going to need auto financing. That's where we are here to help drivers in O'Fallon and the greater St. Louis area. We can go over which plan of action is right for you, whether it is to lease or buy a new vehicle, or used car financing. We work with you to find the best terms possible, as we crunch the numbers and bring you back financing options from a variety of sources. Our goal is to make the experience of buying or leasing a new Mazda fun and fulfilling, and that means providing you with a clear, and hassle-free finance process.

Along with helping you find your new vehicle, we are here to keep it running for as long as possible, too. With our service center, you will find ASE Certified and factory trained technicians to work on your Mazda vehicle or used car, plus, we provide express service for quick maintenance like oil changes, and comprehensive vehicle inspections. We'll also provide you with a loaner vehicle if we need to work on the car for a number of days, and you get a $500 additional trade-in value guarantee if you're looking to upgrade your ride, and you've had your vehicle serviced with us the entire time.
