This purchase has been the best vehicle buying experience
This purchase has been the best vehicle buying experience we have ever had, starting with the online connection with Steven, who handed off to Chandler who was incredible in knowledge, comittment, and follow through... to Eric who worked through our financing. This dealership was fair, helpful, and very detailed. Our pre-owned vehicle had met the detailing investment, and was a real quality investment for us. Looking for brownie points with your wife...chose Spitzer DuBois and look up Chandler to be treated well in the process

Ben Morning is a wonderful salesman!
Ben Morning is a wonderful salesman! I came out to spitzer's to look at a GMC that I had seen online, and it was sold! My eye caught a beautiful, white SUV sitting there and I asked Ben if it was sold and he said no! I took it for a test drive and when I returned, he said that I was the first one to test drive it and that it hasn't even been through service yet! I told him I wanted it! Ben made this process very smooth for me and I am now a proud owner of a 2019 Nissan Pathfinder! Thank you very much Spitzer Auto world and Ben! I'm definitely a happy camper ☺️

We have never had a more knowledgeable, and helpful
We have never had a more knowledgeable, and helpful salesperson (Ben Morning). We would definitely purchase another vehicle from him. The only complaint I have which was NOT his fault. The dealership did not clean the car! It wasn't even vacuumed. Stones and leaves still in the interior and smudges on the seats. Leaves under the hood. Cleaning a car should be a given when purchasing a car. We already made 3 trips to the dealership to get things done so I just took the car dirty. Good thing the salesperson, Ben, was so terrific to make up for the garages down fall.

I have dealt with Johnson and spitzer and the service is good. Except this time the deal went great I ordered accessories for my 2026 GMC Canyon I took time off work to get it done was told all the accessories were in but to find out only the tonto cover was in I was given a loaner which I had to put gas in so this part of the deal im not to excited about.
