The Transportation Center of WNY
I just recently purchased a used vehicle from the Transportation Center of WNY. I specifically dealt with the salesperson Darell Means who was personable and very knowledgeable about the inventory being sold. When purchasing a used vehicle notably there will be certain mechanical issues that may need to be addressed and in my case, these issues were addressed and resolved as quickly as possible. Thank you Mr. Means for your above-board salesman-ship. I recommend The Transportation Center of WNY.
Nice for what it is
Meets my needs. Plenty of power. Lots of room. Hauls and tows like a dream. Very nice and stylish truck considering that it is a W/T.

Easy no pressure experience.
Easy no pressure experience. Had the truck ready for me when I arrived no mechanical issues and a fair price.
Most dependable truck i ever owned.
This truck is a beast, but with the Duramax diesel engine, its fuel efficient as well. my best average is 21 mpg which is insane for a truck this size.

Couldn't be more pleased, Brandon the sales manager
Couldn't be more pleased, Brandon the sales manager actually took care of us from start to finish. There was no hi pressure sales, no back and forth and no games. It honestly was relieving. He helped me with financing and had me out the door in less than one hour. I'll definitely be back and highly recommend.
Loved the Duramax Diesel and an incredible truck
Incredible truck. Wanted to trade it in for a 2020 same truck but unfortunately the interior for this year hasn't been updated. Supposed to next year. Will check in then. Would never consider a Ford or Dodge over this powerhouse.

Mountaintop for life. Awesome experience
Found me a truck that I have been looking for. Had several on the lot but I’m very picky and knew what I wanted. Since they didn’t have the exact thing u was looking for, the salesman spent the rest of the day finding my truck. He went personally and picked it up and got it through service very fast and I was ready to roll with all tests ran and a great truck on top of it. Absolutely would go to this dealership again. Looking for a car and an SUV next year for the family. I will definitely be going back when I’m ready to pull the trigger on my/our next vehicles
