Best car buying experience ever.
Larry Marcus was our sales consultant and Kendra Milan was our Finance Manager on our visit . From the time my wife and I walked in Larry us made feel at ease. Working thru the sales process with Larry was very smooth. We never felt any pressure during the time we were with him. He was very knowledgeable about the Acadia we were looking to purchase. When we were first looking at the vehicle he answered all of our questions. When it was time to leave with our new Acadia he took time to review the features of the vehicle before we left. He helped us set up some of the technology features during that time. Kendra Milan made the financing part of the purchase very easy. She was was very helpful and knowledgable going over all the paperwork necessary to purchase a new vehicle. Like Larry there was no pressure at all while working with Kendra. We were very impressed that we could come in and leave with a new vehicle on the same day. My wife and I agreed that this was one of the best car purchasing experiences we have ever had. We arrived at 2:30pm and were driving away by 6:30pm with a new Acadia. I would highly recommend Albrecht Buick GMC and Larry Marcus looking to purchase a Buick or GMC.

I bought a hard-to-find truck remotely.
I bought a hard-to-find truck remotely. Joel Picchi made the sale easy, answering all my questions, and helping navigate the challenges of an out-of state purchase. It ended up being one of the smoothest purchases ever! Thanks to the team for getting this awesome vehicle delivered to my home in central Maine!

?????????? 5/5 ? Outstanding Experience from Start to
?????????? 5/5 ? Outstanding Experience from Start to Finish! I recently purchased a Hummer from GMC and had the absolute best experience I've ever had at a car dealership. Jacob M. was incredible to work with?professional, friendly, and genuinely dedicated to making the process smooth and enjoyable. From the moment I arrived, Jacob made me feel welcome and informed. He answered all of my questions, took the time to explain everything about the vehicle, and never once made me feel pressured. His knowledge and honesty were a breath of fresh air. I also want to give a huge shout-out to the entire team?from sales to financing. Everyone I worked with was courteous, efficient, and made me feel like a valued customer. They helped me pick out the perfect vehicle and made the financing process simple and transparent. If you?re looking for a top-notch dealership experience, I highly recommend stopping by and asking for Jacob M. and his team. They made this Hummer purchase one to remember!

Great service, great people
I had a fabulous experience purchasing my Sierra. There is NO pressure which is a breath of fresh air. They are extremely knowledgeable, kind, trustworthy, and you will feel very confident in buying from them. I go there for service too and everyone remembers who you are and they come up to you to say hello. If I could give them more stars I would. This dealer is exquisite.

I called Vendetti Motors when the tire monitor light came
I called Vendetti Motors when the tire monitor light came on and showed no reading for the right front tire. The tire was not flat. The service manager fit me in the next day. After testing it was determined that the sensor for that tire was not working. It could not be reset. After being advised of this I asked the service manager to replace it while I waited. Vendetti?s service department is dependable, efficient and courteous.

Second time using Martys and very happy!
Can't get better than Marty's! We purchased a new 2021 Acadia through Marty's this go-around and had the pleasure of doing business with Paul. Great sense of humor, but even better businessman. We showed him a great offer from a competing dealership up in NH, that every other local dealership around here told us was impossible to make. Paul disappeared for a few minutes came back and said I can match that! So happy with the car, and happy we got to continue our relationship with Martys.
