One of the Best Buying Experiences!
I recently purchased a pre-owned vehicle at the AutoMax in Framingham. I have bought many cars in my lifetime but I can honestly say, this was one of the best car buying experiences I've had in a long time. This was my first time at AutoMax of Framingham and I was able to find the right vehicle, with the right options and at a fair price (compared to your competitors). However, what really made the experience worthwhile and very appreciable was the salesperson Matheus. "Matt" is really a great salesperson. Much different from others I have met and dealt with. Matt is extremely Knowledgeable and professional - Great Hire and Asset! I will continue to do future business with AutoMax and will refer my family and friends as well. Mark
