Ira Lexus review
Every aspect was amazing.
Every aspect was amazing. From the valet who greeted me when I arrived to the car washer when my car was ready. Dennis was his amazing self. Arranging my loaner to keeping me updated on my vehicle as it worked it's way through the shop. Video showing me my vehicles inspection is a great feature.
2021 Audi A6 45 Premium Plus review
Very nice upscale vehicle. Bought as a previously
Very nice upscale vehicle. Bought as a previously 2 yr leased auto, avoiding new car price and immediate depreciation. V-6 engine has no hesitation and quietness is excellent. My only two negatives are lack of storage for incidentals and a bit quirky audio that may reset from time to time ( must wait for it to go through a cycle). It has a mind of its own. Overall, excellent vehicle.

Jose was great.
Jose was great. So friendly and easy to work with. No pressure. He wants you to feel great and will do anything he can for you. Tyler and Chris were great too! Alex is also very reasonable and also does not apply high pressure.

Audi Nashua review
Awesome Audi experience
I had an awesome car buying experience at Audi Nashua with Matt labrecque. Through the whole experience I felt like I was the number one priority. Matt was always there if I had any questions and really wanted to sell me a car that I would enjoy. I never felt like pressured into buying something I didn't want. The recon department also did an amazing job detailing the car. The interior, exterior, and engine bay looked great. The finance department also gave me a lot of usual information like how I can refinance my loan and get a lower interest rate. Overall I had an awesome Audi experience and I love my new to me s4!

Nice staff.
Nice staff. Very low key, transparent sales pricing. Even the used vehicles are well cared for and clean.
2021 Audi A6 55 Premium Plus review
Beautiful Meh
Leased the car for looks new in 2021. Now 2023 with 28k miles. Perfect? No. Awful? Hardly. Many recalls but no maintenance issues whatsoever. Biggest complaint is the auto-start stop and that the electronics are quirky (pre-set destinations reset frequently) car is comfortable, quiet, quick, and get OK gas mileage (would assume better with 2.0 4cyl.) I often switch between this and a 2017 Honda Accord and to be honest I can't tell much of a difference other than noise and quickness. Will buy it off lease (got it before the residual values rose exponentially) and will keep it indefinitely.

Karl was a wonderful salesman.
Karl was a wonderful salesman. I would refer him and both my husband and I would buy from him again. Every sales experience should be as great as the one we had. Great job Karl!!!
