Gold star treatment
Went to 3 other dealers before being reccomend to matt Harris and knew instantly it was our last stop. We has been treated like xxxx at the other dealers. 1 lied to us and another told us he would not replace bald tires on a 2 year old luxury vehicle. The second we met Matt we knew we were In great hands. My fiance got the Mercedes she wanted at a fair price and the vehicle recieved everything it needed in the shop before we looked at it. The finance guy treated us like human being and never once felt like I was being had. Oh I forgot to mention that I sold cars for the last 17 years so I recognized great people right away. We will always be loyal to Matt and appreciate everything he did for us

I usually get SUVs or Trucks from American Brands. I wanted to get my self a really nice seadan. My buddy recommended me to go to Mercedes-Benz of Burlington before I go to any other luxury dealership. His recommendation was spot-on. Dealership is beautiful with a waterfall fountain plus a nice cafe. The staff is extremely accommodating. I met Collin Stankard valet who took me to TJ a sales associate. TJ was patient and helped me find the right car for my needs. Chris Caputo GSM took the time and found the proper numbers to make me happy because I like to haggle. Then I sat down with Steve Baker a finance manager me made the paperwork easy peasy. Elaine PC had an awesome delivery for me. I learned the ins and outs of the car. Tim Martino the GM was out on vacation but made sure that everything was done properly and I was treated like a VIP. My father was in the car industry. I know the games and gimmicks the people like to run. I'm extremely happy that I only had to go to one place and had a great experience. I'm now part of the mbob family.

I have worked with Brian for quite a while and I have been exceptionally pleased with the service that he has given me. I feel very comfortable having Brian in charge with the service department because he stays on top of what has to be done. I have found that Brian is very caring, professional, and knowledgeable and when I leave the dealership I know that everything was done perfectly. Janet Edsall Fields
