Will return for service
Had a recall and lube/oil/filter service, which all went well. My only interaction was with Joel, and he has a great attitude and provided excellent customer service.
Sophisticated Performance Sedan
I purchased the 2021 Audi S6 Prestige after looking at similar vehicles in the class like the BMW M550i and Mercedes Benz AMG E53. My choice came down to performance, reliability, look, and value. I have had the car for 4 weeks and have no regrets. My highway gas mileage has been as high as 31 miles per gallon which is terrific for a car with this type of performance. The controls are easy to learn and the car feels like it is floating when driving it. I like that it is a performance vehicle with an understated look. Some may want a car with a more aggressive look but I like the understated, traditional sedan look. So far I would recommend this car.

"I recently purchased a car from Autobahn Dedham, and I
"I recently purchased a car from Autobahn Dedham, and I couldn’t be happier with the experience. From the moment I walked in, the salesman, Peter, was incredibly helpful and knowledgeable. He took the time to understand my needs and budget, and guided me through every step of the process. There was no pressure, just honest advice and great customer service. The car selection was excellent, and I felt confident in my decision. I highly recommend Peter and Autobahn to anyone in the market for a new vehicle!

I recently had the pleasure of visiting Leman’s Cars in
I recently had the pleasure of visiting Leman’s Cars in Commack, and I cannot express enough how impressed I am with the level of service we received. My 19-year-old daughter, excited about her dream car—a 2015 Dodge Challenger R/T Scat Pack—stopped by the dealership with a friend and was treated with utmost respect and dignity by the sales team. She came home raving about her experience, and as a skeptical father, I was initially hesitant. However, her enthusiasm was contagious, and I agreed to accompany her the next day. From the moment we arrived, we were greeted not just by one, but two salesmen who remembered my daughter from her previous visit. They welcomed her like an old friend, which immediately put us at ease. After spending a couple of hours with Christopher B. and Jack, I realized this was no ordinary used car dealership. These gentlemen were honest, straightforward, and genuinely cared about our experience. Jack took the time to explain everything about the financing process to my daughter, ensuring she understood how loans work, down payments, and refinancing options. It was refreshing to see such transparency, especially in an industry often plagued by skepticism. I am thrilled to say that my daughter is now the proud owner of her dream car, and the entire process was seamless. The loan representative from the bank even shared in our excitement during the welcome call, confirming that everything was as promised. If you’re looking for a car dealership on Long Island, I highly recommend Leman’s Cars in Commack. They have proven to be a trustworthy, respectful, and friendly establishment. If you visit, make sure to ask for Christopher B. or Jack and mention that you read our review. I’m confident they will exceed your expectations just as they did for us. Used car shopping can often be stressful and filled with gimmicks, but Leman’s Cars is a breath of fresh air. Don’t waste your time elsewhere—start your car-buying journey with them first! You won’t regret it! Thank you, Leman’s Cars, for making my daughter’s dream come true! — Paul
