My Sixth Mercedes Benz-Fantastic Cars
The GLS has the luxury of a sedan and the versatility of an SUV. This is the fourth GL series that I have had and would not consider another vehicle.

Coming from another dealer closer to home I had
Coming from another dealer closer to home I had discovered Fields BMW in Northfield. Their customer service is top notch to other BMW dealers I have been to and I have since taken my service and sales business here and have leased my past two vehicles with Fields Auto Group. Ask for Carrie Shapiro, senior client advisor and she will take the upmost care of you! Everyone in the service department is pleasant to work with! In the past have worked with Jerry M., Ed P, and Chris Goodrich and they all take care of you with the same level of care.
Solid well build automobile

I had an outstanding experience with BG Motor Cars!
I had an outstanding experience with BG Motor Cars! From the moment I walked in, the team was welcoming, friendly, and attentive. They have an impressive selection of quality vehicles, and I found exactly what I was looking for at a great price. The staff made the entire buying process seamless, providing detailed information and answering all my questions without any pressure. What stood out most was their transparency and professionalism — I felt confident every step of the way. The car I purchased was in excellent condition, and they took the time to ensure everything was in order before I drove off the lot. If you’re in the market for a used car, I highly recommend BG Motor Cars. They truly go above and beyond to ensure a top-notch customer experience!

I love Muller Honda
I'm from Chicago but grew dissatisfied with the crappy service city dealers gave me so I traveled some distance away from the city to Muller Honda and I'll tell you my experience was fabulous . I came in for an oil change, rear differential fluid change and tire rotation. I fell in love at first sight with their service area set up and their transparency to do business. You can actually see them working on your car real time not like the city dealers that kidnap your car for 2 hours and you don't see what's being done or not being done. The price was right, the atmosphere was clean and relaxing. Muller< I love you guys, this was my first time here and I can assure you it won't be my last.
There are 20 matching cars close to your year range.
