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.
