Great selection of cars.
Great selection of cars. I bought my Tesla at Affinity and couldn't be happier. After going to a few different places Affinity had the cleanest and by far the best service. I will be back again when the time comes.
Best SUV we've ever owned.
Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

I was looking for a 2022 Navigator and Driven Auto had
I was looking for a 2022 Navigator and Driven Auto had the only one in a 300 mile radius for a competitive price. The pictures of the vehicle were excellent, so I requested more info and their salesman Basil got back with me. He was extremely helpful and even checked to see if I could reserve the vehicle since I was out of state and it was Saturday and couldn't get into the dealership until Monday. I scheduled a trip to the dealership and let Basil know. When I got to the dealership, the car was washed and ready for me. The detailing was top notch. Basil was helpful and not pushy at all. He answered any and all questions and worked with my bank to get the purchase finalized. When the paperwork was signed, they didn't try to sell me a bunch of extra things. I really appreciated that. Overall it was very pleasant experience and everything went smoothly. The price was very competitive across 3 states, and Basil was very helpful and pleasant to interact with. I saw several reviews complain that Driven Auto didn't hold a car and sold it before they got there, so yes it really is first come first serve, but to me that is completely understandable and was communicated very clearly to me. 5 out of 5 would buy there again.
You get what you pay for
We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.

Price listed is the price you pay!
Dealt with this CarMax dealer over the phone and email. Tried to negotiate a price based on other dealers in the area for the same vehicle and was told that the price listed was the price you pay!
Great Electronics and Engineering
This car is state of the art in human factors engineering. It has multiple layers of safety enhancements. Interior is very spacious. The 42 volt battery provides quick acceleration which allows the car to have no lag time when accelerating.

We purchased a 2024 Corvette spur of the moment. (No regrets!) From the moment I walked in, I was immediately taken care of. Kim was amazing from start to finish- she was sweet / funny! The process did not take as along as we would at any other dealer. I would definitely be coming back for any other purchases we may need in the future!

I wanted to get a car fairly quickly and knew what I was
I wanted to get a car fairly quickly and knew what I was willing to spend. My salesperson Paolo was extremely helpful and found me my car in the color I wanted in less than a week. To my surprise, the package I purchased even came with several bonus accessories for protecting the interior. Paolo took his time with me and explained every feature in the car (even after closing), which was amazing since the manual looks like an encyclopedia. The dealership followed up later with a Zoom call to answer any additional questions I still had and they’re sending me a free gift! Overall, I would absolutely shop here again and recommend this dealership to my friends!

I am writing to express my sincere appreciation for the outstanding service I received during my recent visit to your dealership. As a loyal customer who has now purchased three cars from your establishment, I felt compelled to share my positive experience with you. The team at Ultima motors truly embodies the meaning of exceptional customer service. From the moment I walked in, I was greeted by amazing staff who made the entire car buying process incredibly smooth and hassle-free. Not only did they streamline the process, but they also managed to secure a fantastic deal for me. I must particularly thank Chris from the Sales department for his professionalism and helpful demeanor throughout the transaction. His dedication to ensuring customer satisfaction is truly commendable, and I will not hesitate to recommend him to family and friends who are in the market for a new car. Furthermore, I was impressed by the overall organization and efficiency of the management . It is evident that the entire team is committed to delivering prompt and high-quality service to every customer. The quick and professional service I received further added to the overall positive experience, solidifying my decision to continue purchasing cars from your dealership in the future.

Ziegler Land Rover steals buyers money and cars.
Ziegler Land Rover steals buyers money and cars. They sell new vehicles to you and then negligently deliver this to someone else with no any proper documentation. When you request your car or money back they simply kick you out declaring that deal is done. Then they steal your sales tax money and they try to register the stolen vehicle on your name. General manager and new cars sales manager are making at you telling to go to the insurance company. But there is no any insurance because the vehicle wears never delivered. Do not buy any cars from this fat cockroach. They are thief.
There are 20 matching cars close to your year range.
