I purchased a vehicle from Autobahn USA Dedham about a month ago and couldn't have been any happier. I worked with Peter and let me tell you he was great in all aspects. He took his time explaining everything regarding the vehicle and answered any questions my family and I had. He is extremely professional but also has a humorous side, which made the entire process even better. He was very understanding and helped us find the right car that worked with our budget. If you are considering buying a vehicle with them I recommend it, given to me in great condition. And if you want a greater/smoother experience then ask for Peter! :)

If I could give 10 stars I would!
If I could give 10 stars I would!!! I recently had the pleasure of purchasing a used Porsche, and the entire experience has exceeded every expectation I had. From the moment I began inquiring about the car, the dealership was responsive, professional, and incredibly thorough. Despite the car being located in Boston, I was initially hesitant about the logistics of having it delivered all the way to Indiana. But the dealership went above and beyond to make the entire process seamless. Timothy Klingenberger specifically was a DREAM to work with and someone I now call a true friend. He had my best interest in mind from start to finish. I can’t usually say that about any car dealership. Tim provided detailed photos and videos of the car, ensuring I could make an informed decision from a distance. The condition of the Porsche was exactly as described, and when it arrived, it was even better than expected—immaculate, with every feature working flawlessly. It was clear that the car had been meticulously cared for, and the quality of the vehicle far surpassed anything I’ve ever experienced in a used car. Not to mention and without my asking Tim included a second key fob at no additional ask or charge to ensure I had two as it would have come with when purchased new. The delivery process itself was smooth and efficient. The car arrived on time, in pristine condition, and with a full inspection report included. It was evident that the team cared about customer satisfaction and that they were willing to put in the extra effort to ensure I was thrilled with my purchase. What really stood out to me was the attention to detail and customer care Tim gave me from start to finish. I’ve owned several high-end cars, but this was by far the most seamless and satisfying purchase I’ve ever made and I can be picky. If you’re considering buying a car, I would highly recommend this dealership. They truly went the extra mile, and I couldn’t be happier with my decision.
Perfect sports sedan, TDI engine is amazing!
Bought my '16 A6 3.0 TDI a year ago with 89k miles, now has almost 110k miles, and drives like a dream still. Can't even tell it's a diesel engine by the way it drives and how quiet it is. I drive a lot for work, and the gas mileage is amazing! Interior is comfy, classy, and roomy. Drives like butter, handles like a sports car. Exterior isn't too flashy, it's perfect. No issues, and my last checkup at the German export dealer was perfect. My favorite car I've owned, now I want an A8 L!

Carmart is a professionally managed business.
Carmart is a professionally managed business. The places I went to before could not find a financing method for me. However, when I went to Carmart, Mustafa patiently took care of me and made expert moves in financing transactions. Thanks to this, I was able to buy my car. I thank them very much.
Excellent choice
This is a fun, responsive, reliable, well built car to drive. At over 75K miles now, and I really cannot even consider trading it in because I don't think I will enjoy a better ride.

I had an incredible experience working with Mike Morris.
I had an incredible experience working with Mike Morris. He went above and beyond to help me find the perfect car for my wife it ended up being the best gift I could’ve ever given her. Mike was patient, knowledgeable, and genuinely cared about finding exactly what we wanted. He made the entire process smooth, stress-free, and enjoyable from start to finish. It’s rare to find someone who combines professionalism with such a personal touch, but Mike did exactly that. If you’re looking for someone who truly listens and delivers an exceptional experience, I highly recommend Mike Morris. He made this a moment we’ll always remember!
Must buy at a realistic price.
Such a gorgeous vehicle, inside and out. Haven’t had a single issue with it for over a year of having it used. Inside of the vehicle is super roomy, and driving feels very comfortable, and really we’ll insulated!

As always, the staff was prompt to find out what was wrong and send the car to mechanic?s staff to determine. In this case, it was a 70000 mile check up and they determined all was in order and released my car with a wash and a quick release.

I had a wonderful experience today purchasing a pre-owned
I had a wonderful experience today purchasing a pre-owned Infiniti from Car Lot Express! I first discovered them on Facebook Marketplace, where I found a car that caught my interest. Thereafter, I contacted the seller by phone, and he warmly invited me to visit their dealership. When I arrived, I was greeted kindly and given the opportunity to check out the car in person. The Infiniti looked fantastic and matched exactly what I had in mind. After a friendly and honest discussion, we finalized the deal and completed the purchase.
Pure luxury
This Audi is beautiful, inside and out, with genuine wood in the door panels, dash and center console, soft leather seats, and a massive amount of red light illumination throughout the front cockpit, that is fantastic while driving at night. The exterior is sleek and stylish. The ride is smooth, however the low profile tires do ruin some of the ride atleast on kansas roads that are far from smooth. The engine has no vibrations and suspension seems tight . All in all this is as close to perfection as it gets, German cars are the best.

Would go back again if needs be
I went over to explore my options and was focused on a car located on the website until I seen one that stood out Lee and staff was patient& pleasant both lol as xxxx,And have referred folks to them
Perfect blend of Form and Function
Surprisingly powerful, effortlessly elegant, and large enough to adapt to your lifestyle. This car does it all. 300 hp, a performance driving experience, and a roomy back seat for a car seat all in one vehicle. Lay the back seats down and there?s room for two bikes to be fit into the trunk. 30 mpg highway. Smooth, powerful, and understated. This car is a must have.
