Ram Truck
The air suspension system in my truck is TERRIBLE! I cannot believe the manufacturer has not done something to address the flawed design and repeated dysfunction of this feature of these trucks!
well put together vehicle
The truck met all my expectations and more so far. the engine is powerful and the ride is smooth. the interior is great and so are the things this truck has.

I couldn't believe how easy it was!
I couldn't believe how easy it was! Amy Mendoza and Salvador were excellent in their knowledge about the vehicle I wanted. It only took 2 days to get everything done. Great team work. The best experience I've ever had buying a vehicle.
Versatile and comfortable hauler
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.

Great truck
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.

Michael and the crew were absolutely amazing.
Michael and the crew were absolutely amazing. I bought my daughter a 2016 wrangler from the team and I couldn't be happier. The most personable local dealership around. They helped from A-Z. Financing, securing the car - and we left happier than a chipmunk. Thanks again fellas.

Great people, great car!
I drove by here on my to another dealer. I didn't realize the dealership was there (not from the area originally) and I turned around to see what they had. There was no haggling, no debating, no arguing, no lying, no cheating, no stealing-all things you can expect at some dealers. These guys were all top notch individuals who I could hang out with all day every day. I felt a bond with Mitzy, the dog who kept trying to untie my shoes. Maybe she was persuading me to stay and buy a car? That's exactly what I did. I bought a three-year-old Jeep at a good price with a good interest rate. I wasn't expecting to actually buy a car there, let alone finance one, but I did and my wife is thrilled with her new Jeep. I highly recommend Lou Dominion's Deals On Wheels Benton Harbor location. If his two other locations are anything like this one, you won't go wrong at any of them. I also highly recommend Phil the salesman. He's the real deal, a genuine, honest to goodness human being. No games from this guy and I respect that entirely. If you've read this far, you know I'm pretty satisfied with everything. I am. Best car buying experience I've ever had and I will go there first when I buy my next car!

They were very helpful and totally gave me as much information about the vehicle needed. There location is just to far from where I live and the extra expense to fly and drive for two days to arrive back home just made it expensive for me. Thank You for your assistance.
