What a positive experience from beginning to end.
What a positive experience from beginning to end. I never did business with ActonToyota previously. I was in the market for a used vehicle and Ron a very talented and knowledgeable sales person reached out to me and helped me identify exactly what vehicle I needed and gave me great suggestions and options. He allowed me to test drive the vehicle that I identified and worked with me to get the best price possible. It was a used car and he introduced me to Jeff The manager overseeing that department. What an experience and a very genuine honest individual who educated me on the different vehicles mentioning not only the positive, but also some of the downsides of owning a particular vehicle, including high maintenance costs or gas mileage concerns. In addition to Ron and Jeff. I was very pleased with the finance department in terms of how easy the process was and allowing me to pick and choose which Service plans if any work best for me. Jo and Josiah were awesome to work with. I have owned and purchased a number of vehicles from other dealerships. Normally the finance people are very formal and can Sometimes make the consumer, uncomfortable and anxious. It was the complete opposite with these guys. One last shout out to Jimmy and his talented team over at Acton Toyota! Jimmy came up to me and introduced himself and was as down-to-earth and friendly as one could imagine. I really felt like I knew the guy for years. The whole process was awesome and the people there made it so comfortable and easy to purchase a vehicle that I would highly recommend anyone looking for a vehicle to at least give them a try. I’m sure that you will walk out with the same positive experience as I did.

I had a great experience working with Nate Resendes.
I had a great experience working with Nate Resendes. He was incredibly attentive and knowledgeable, taking the time to answer all my questions without ever making me feel pressured to buy. I appreciated how understanding he was about my situation — I’m not quite ready to make a purchase yet, but wanted to get a clear idea of what to expect. He gave me helpful, honest information and made the whole experience comfortable and informative. When I am ready to buy, I’ll definitely be coming back to work with him specifically. Highly recommend!
Best truck I ever owned
Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

All I can say is WOW!
All I can say is WOW! I haven’t always had good luck buying cars and got myself into a jam. Neil Peabody was so amazing! He got me into the perfect SUV, he was fast pleasant and to the point Ian and Tim were also so nice and able to help me out in just ONE DAY! I can’t say enough good things about these guys and their customer service A++
Great Truck (sans MPG)
Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

Definitely worthy of your consideration to see Manny Williams I had done my homework on comparing other dealerships to compare like vehicles in price, size and driving experience. He will work with you patiently answering all your concerns of comparisons and pricing.
Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

I buy a new truck every 5 years. Always great service . Nick Cardillo is my go to guy. All departments are great to deal with.
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Second time using Martys and very happy!
Can't get better than Marty's! We purchased a new 2021 Acadia through Marty's this go-around and had the pleasure of doing business with Paul. Great sense of humor, but even better businessman. We showed him a great offer from a competing dealership up in NH, that every other local dealership around here told us was impossible to make. Paul disappeared for a few minutes came back and said I can match that! So happy with the car, and happy we got to continue our relationship with Martys.

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.
