This was absolutely the best experience I have ever had
This was absolutely the best experience I have ever had at an automobile dealership. The Salesman Bryan Struzynski was terrific to work with and Ray Wojcik the Business Manager was as well. We walked away with a great experience and a new truck.
2020 GMC 2500 AT4
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.
There are 4 matching cars close to your year range.
