Used GMC cars for sale near Marengo, IA under $599,963

Awesome experience each time. Great team and very helpful. Always looking out and helping with each step of the process. Thanks again for our second new Honda!

I had my oil changed with no concerns. Staff was nice.

I saw this car driving by the dealership and automatically was drawn to it because of its color. GMC calls it brown but one print out called it crystal metallic purple. It changes colors depending on the weather. I love the handling, the dash and all the bells and whistles! My grandchildren love how much room that it has!

I have always taken my cars to McGrath and they have always treated me great , Tyler and the rest of the service department is always friendly and greets you with a smile. They take the time to explain everything and make sure you understand everything,

They do a wonderful job maintaining my vehicle. Great customer service.

So far the car is going great. We have had no problems driving everywhere and so far had no need for services. It is a great care for me and my husband,

Not sure what to say. I need help getting the truck I like most. Have to see what happens.

Josh was super helpful and made the experience very smooth! He answered all of my questions and while I was at Cassill I was confident I was getting a great car at a great deal.

Just trade in my 2015 GMC Denali with 140000 miles on it and still holding strong at trade in best SUV I ever had upgraded to the new 2021 Denali and boy do I love this SUV from comfort to outside design just an amazing new well designed SUV.

Salesman was excellent, finance was excellent. Its hard to complain when you show up at 4:30 the car is little bit dirty and needs fuel. But they handled it all quite well. This was even on a Iowa Hawkeye football weekend! They have some very nice stuff on the lot, and the showroom too!. I loved looking over the selection of Trucks and especially the New Dodge Challengers! No High pressure gimmicks, just honest people making a living doing what they like to do!

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

My family and I have purchased 9 cars from Four Guys Auto. They have always sold us good quality cars. But, above that they have always been honest and trustworthy. They have gone above and beyond the listed warranty. When purchasing a vehicle, they have always been straight forward about the pros and cons of the vehicle. If they vehicle was expensive to work on, they would tell us. If the vehicle got bad gas mileage, they would tell us. If there was anything wrong the vehicle, they would tell us. Over the years, they have become family. I think that's because they never once tried to "sell" us a car. They are simply good at what they do, and have a passion for what they do. Places like Four Guys Auto are hard to find. Support a local, family owned business.

This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!

Devon Canty was great to work with on an out of state purchase. We got a great car at an amazing price.

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

I have just started to look for a new vehicle. My experience at Deery Brothers was wonderful. Jordan was very helpful and knowledgeable. I am looking forward to working with him when I am ready to buy.. I will definitely recommend this dealership to my friends and family.

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.
