The dealership had a great selection of quality used
The dealership had a great selection of quality used cars, all well-maintained and reasonably priced. I appreciated their transparency and honesty throughout the process, including providing detailed vehicle history reports. The financing process was also seamless, offering several options and explaining everything clearly. I left feeling confident and satisfied with my purchase. Overall, I highly recommend Affinity Auto Sales to anyone looking for a reliable used car and a pleasant buying experience. Thank you to the entire team for making this such a positive experience!
New Mustangs are fantastic 👏
For the money it is hard to beat a new Mustang on any trim level but especially the 5.0. Also the 10 speed automatic is a fantastic transmission as it keeps the engine in the powerband when asking for performance.

Brazil at Driven Auto of Oak Forest was AMAZING.
Brazil at Driven Auto of Oak Forest was AMAZING. He was very helpful and knowledgeable. Amir the finance manager was patient, understanding and helpful.
Magnaride
Highly recommend Magnaride with Performance Group 1. Lowered the car within Magnaride specs and the car handles so much better. The chassis is rock solid even in convertible style as long as you get the performance pack

Buying from D&M was great , the vehicle I purchased was
Buying from D&M was great , the vehicle I purchased was better than advertised. Communication with Kevin was very responsive and accepting to questions. I sent a mechanic to check car before purchase who was give full access. I dislike the buying process at dealerships, this experience was “what you see is what you get” no bait and switch, price advertised was the price. Highly recommended.
