Very easy to work with!
Very easy to work with!!! I found the Honda certified used vehicle that I wanted online. They actually had the salesperson Hunter drive the vehicle to Bedford NH so I could test drive it and they could appraise my trade-in at the same time. I financed through my local credit union so everything came together for me to pick up the car the following Saturday. No pressure, no hassle, no haggling!!! I definitely recommend!!!

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.

Recall service, 1st. time visit 2016 Sierra
Purchased my vehicle new from dealer 40 miles from home, original preferred dealer closed . Choose Tulley due to location (15mi.) and positive feedback from my son who had service performed on his vehicle. First time at this dealer so it was a little confusing on where to go but I figured it out was pointed to waiting area and ultimately had to ask were to pay bill and retrieve keys. Suggest that for first time visit some direction on where/how to bring vehicle in for service also an escort to waiting area and pointing out. rest rooms, payment area etc.. My only concern was that whoever worked on my vehicle transferred cigarette smoke odor into interior of my truck either from their clothing, hands or location/proximity to smoking area. Drove home with windows opened and left them partially down overnight to resolve/abate issue. I was genuinely pleased with with prompt recall service and will definitely return and perhaps purchase next vehicle from Tulley
