Marsh Auto Sales LLC review
Great experience and stayed late to help us get in a great vehicle, Joey took great care of us
2015 GMC Sierra 3500 review
This is a very clean, serviced and useable truck. I "live" in my truck and needed reliability, but without the garish price of new. All my tools fit and it is very handsome interior and exterior.

KT Automall review
Great experience overall!! Professional and transparent. Called and asked them the out the door price on my Chevy I purchased with them and gave me all of the information I needed before I took the 4 hour trip. My truck is just like I saw it on photos. This is the place where you should buy your car.
2015 GMC Sierra 3500 review
This SRW truck carries a slide-in truck camper and tows a boat when it's not a daily driver. The gas 6.0L is very capable to handle both and the truck is comfortable riding when not loaded down. Reliable engine and truck.

Koppy Motors of Forest LakeReviews
Koppy Motors of Forest Lake review
I just purchased a Hyundai Elantra from Koppy Motors, and I couldn't be more pleased with it. DeAnna was the salesperson who worked with me, and she was OUTSTANDING!! She was polite, cordial, and extremely professional throughout the process, as were the other staff people in the office. The entire process went very smoothly. DeAnna walked me through each step and appeared to be highly knowledgeable about many of the vehicles on the lot while we were "exploring" a possible purchase. I would recommend Koppy Motors to anyone looking for a great car, and especially DeAnna as the salesperson to work with. Thank you so much. Mike ODonnell Forest Lake
