Can never say enough about how glad I am that I chose to
Can never say enough about how glad I am that I chose to return to Thompson's for my second GMC purchase. The first time Bobby D. was so helpful that I requested him 2 years later when I returned. He does not pressure you. He finds out what you are interested in and why, how will you use it? He then gives you options that are available. He was able to answer all kinds of questions about how the vehicle operated etc. He is so likeable. I wish everyone who deals with the public was as polite, understanding, knowledgeable and on and on as he is. THANK YOU BOBBY! Oh Yeah, I like my 2 vehicles too!!
Great Diesel truck when emission sensors work
Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

Rapid emergency help on a long round trip!
Traveling from Lewes, DE to Fargo, ND for a family reunion on a very tight timeline a belt in one of our tires failed. We luckily found this wonderful dealership nearby! Nathan in the service center & their excellent technicians fit us into their schedule that day!!! The sales staff made our stay in their show room a very friendly & accommodating experience traveling with a small dog. We can’t thank everyone enough for your excellent service & kindness during this stressful situation. We made it to the reunion thanks to all of you!!! 😎 Tina, Lynn, & Carly 🚙🐩
Great car for work!!
Comfort, ease of driving, style, convenient for work and we LOVE the tailgate! Great for towing our heavy fifth wheel and our dogs are riding in style!!

This is my 5th purchase from Mike Castrucci Ford.
This is my 5th purchase from Mike Castrucci Ford. Josh Holston and Jerome Fix as well as the finance department is outstanding. Fast, EZ to deal with and straight forward , no xx Ford sales. Josh was great in explaining everything in my new F150 and was very patient in showing me different trim levels. No need to go anywhere else for sales and service.
Great luxury ride with great pulling capabilities.
The Texas Edition combined with the X31 package and premium SLT makes a very nice combination. The Sierra 3500HD gives you a luxury interior and ride with all the capabilities of a great pulling truck. The Duramax is quiet yet powerful. It is no doubt the best of trucks for 2020.

I recently purchased a vehicle from Champion Chevrolet in
I recently purchased a vehicle from Champion Chevrolet in Howell Michigan. If I had just two words to say about my experience there it would be Logan Richardson. I was fortunate to have had him as my first contact for the vehicle I was looking to purchase. There is not one negative thing I could say about him. A better way of saying that would be everything about dealing with him was 100% positive! He is friendly, knowledgeable, and patient and became my advocate during the negotiation process. He erased all my skepticism about dealing with car salespeople. He has my highest recommendation!
