It was a good experience.
It was a good experience. The lead sales man was a little on the rough side. But all was good.

Best Car Shopping Expereince!
I just picked up my new car at CarMax of Hartford and, I have to say, this was the best car-buying experience I have ever had. I had found a Ford Explorer that I wanted to see on their lot. I put a hold on the vehicle on their website, very early in the morning. By 9am the same morning, I was contacted by Rocco Toce, the most awesome sales person around. I have bought many vehicles through the years and he is the top of the list! We went to look at the truck and he had it clean and ready for us to test drive. We loved the truck but it just didn’t have all the options that we were looking for. I found the exact Explorer we wanted in New York and Rocco jumped right in to help us transfer the vehicle to Hartford. I have to admit, it IS a leap of faith to pay the transfer fee upfront before even seeing the vehicle in person. Rocco jumped in and took over. He spoke to the other CarMax and had them check every part of the vehicle out. I felt very comfortable after he called and told me the truck sounds good. My Explorer made it to Hartford very quickly and Rocco immediately checked it out and let us know it was perfect! I went to see it yesterday. It was beautiful and in the best shape. Rocco took us through the entire car and never rushed us through anything. He sent our Explorer to detailing while my 2009 Silverado was appraised. I received a fair price for my trade and the deal was smooth and handled professionally by the staff. I’m pretty sure I have not had a better car buying experience. Rocco and the team at Hartford CarMax could not have done more to make our experience the best. I did a ton of research about CarMax like I’m sure everyone does. I drove over an hour to work with them and I am so glad I did. We walked out of there with a great, shiny Ford Explorer and the greatest car buying experience!

Tim was Great.
Tim was Great. Couldn't be happier with Tim and Central Chevy and our experience. Even though Bertera Chevy's price was little better, we chose Central Chevy ultimately because of Tim- our Sales Rep. Our car buying experience at Central Chevy exceeded all our expectations especially when compared to our last Car buying experience at Toyota. Thank you again folks!

My experience at Northwest Hills Chevrolet was
My experience at Northwest Hills Chevrolet was exceptional. I was treated with the utmost kindness and respect, and accommodations for my special needs were made willingly, and in some cases, without my even needing to ask. My salesman, Phil Musmacker, made everything incredibly easy for me throughout the entire process (honorable mention goes to Brendan Elrick, who followed up on my initial request for info on the Equinox EV, and connected me with Phil). In addition, I never found any reason to question the pricing on the purchase order; everything was straightforward and exactly as I had been told, which is incredible considering my previous experiences with dealerships, where I had to fight to keep extras from being added to my order. Truly remarkable! I've already recommended Northwest Hills Chevy to a couple of friends! Thank you for a most wonderful experience (and I also really love my car)!

I I am very happy with my purchase.
