Wesley was very professional didn’t question my offer
Wesley was very professional didn’t question my offer brought it right to sales manager. Negotiation was smooth in the end I paid what I thought was a fair price and got a powertrain warranty thrown in. They delivered car promptly inspected and filled gas tank. Very positive experience no pressure. Thank you guys at Autobahn Westborough.

Did I have goog experience?
Did I have goog experience? Yes, I did. Johnny Tam did his best, although I didn't want to make the experience but his service was good enough to have me do it. Actually, I have the SR5 2025. Thanks to him and Thanks to Oscar as he didn't act like scam. Most of the managers, they just scamming people, but him, he was ok to provide the best that he could. You guys are very good example, Jhonny, Oscar keep on
Most incredible car I’ve ever owned.
This is my second Mercedes-Benz. It’s absolutely the most incredible car I’ve ever owned. I was blessed to be able to custom order this car to have everything I wanted and more inside and out! It literally came straight from Germany to the dealership for me. It drives like a dream. It’s absolutely gorgeous. The technology inside is so amazing! It can drive economically. It can drive more sporty if you want it to. It has so many options and settings for drivers of all kinds. Needless to say, it’s pure luxury inside. You’ll feel incredibly spoiled!

Haven't put many miles on due to snow and ice.
Not enough miles driven to fairly evaluate but look forward to driving when weather is better. I have high expectations! I'll need time to get used to the console controls.

Steve Grossman made me happy
I had an issue with my Rolls Royce and was not happy. Steve Grossman stepped in and after a few days he made me very happy and really took care of me. As a former dealer and Auto executive Steve Grossman did a great job. I recommend the Veanan group in West Palm

I worked with Tarik to get my 2024 Alfa Romeo Stelvio and it was a really great experience. He was extremely patient through the sales process and took me through all my options and helped me find the best way to get what I wanted. I would certainly recommend using Tarik and the rest of the team at Glenview to purchase another car in the future and recommend them to anyone who's in the market!

I just bought a 2008 bmw 650i from Rick.
I just bought a 2008 bmw 650i from Rick. I am amazed how clean the car is overall but especially the motor. I brought it home and had a chance to take a closer look, not a drop of oil leak and even the air filter was brand new. I can only recommend buying from Rick as he treats his cars and customers with utmost care and respect. Thank you Rick!

I had the pleasure of working with Brian Gideon at SMC
I had the pleasure of working with Brian Gideon at SMC Signature Motorcars, and I couldn’t be happier with the experience. Brian spent some time searching for the perfect car for me, treating the process as if he were buying it for himself. His dedication, attention to detail, and commitment to finding the right match truly set him apart. The result? An absolutely gorgeous car that exceeds my expectations. I highly recommend working with Brian if you’re looking for the perfect vehicle. Thank you, Brian!

I had an exceptional experience buying my car from Duane,
I had an exceptional experience buying my car from Duane, he was an absolute pleasure to work with and went above & beyond to make sure I was taken care of. From the beginning he was transparent, honest, not pushy at all (which is always a good sign) and gave me the most fair price I found after months and months of searching for my exact car (Porsche Macan). There was a rare issue with one of my headlights, Duane made sure I had very nice (and fun) cars to drive while he had it taken care of - he even went as far to detail the car again and provided a ceramic coating which just shows the level of service you can expect from this dealership. I can't speak highly enough of Duane & his whole team - you can feel confident purchasing a luxury car here and know you are buying from the best!
