Always a pleasure to do business with this dealership.
Always a pleasure to do business with this dealership. When I am ready to buy a new vehicle I will purchase from this dealership. I always take my vehicle here for service/repairs.
Am I the only one that has had the instrument panel
Am I the only one that has had the instrument panel completely fail? Mine did YEARS ago. So why is my reliability rating 5? The computer still works, I know how fast I'm going, the Miles remaining on the fuel economy is accurate, and it runs. Everyday. Replaced one hub and bearing, water pump, starter, ignition. A/C doesn't work, but I've got windows (which work if you know exactly where to push the button.) Oh, and the Engine light is always on, because the throttle body really needs a thorough cleaning or replacing. Motor and transmission have been crazy reliable for 20 years on truck bought new October '0 3. Nothing a few hundred dollars wouldn't fix. Though there are several of those, they don't keep me from getting from A to B.

Great place to get a deal on a used vehicle.
Nice folks to deal with, bought a clean used 2008 Chevy Avalanche with 120k for a fair price (Jeff was my salesman). Truck had some minor issues, a missing back up sensor, and a loose plastic panel on the tailgate. They fixed them both asap, and I bought the truck. A good deal all around, I would buy from them again. If you understand the used market, I'm sure you'll find a great deal there on a vehicle.
Best truck, so good I’ve got second one
Bought truck brand new with 9 miles on it other than two water pumps and one fuel pump which were my fault for running on fuel. I haven’t had any complaints other than the guy on the dash peeled off minimal 53 runs great at 200,000 miles reprogrammed truck at 500 miles gets 20 to 22 miles a gallon down the highway as long as you’re on supreme runs great never left me stranded best truck I’ve ever owned I’m in search of another one similar same body style, but a three-quarter ton now but plan on keeping this is long as I can just purchased a brand new 5.3 to put in it when this one wears out it’ll keep going had minor issues with the dash gauges, light one out and a couple of gauges. No big deal, I also have an 03 Chevy Tahoe but it had all of the problems in the Insta rebel had panel replaced $600. No other issues. Great track Holly

Reliable As Can Be
Bought my 03' Sierra 1500 as a first vehicle. It was an extended cab with the 5.3 litre Vortec. After 245,000 miles I have had VERY FEW ISSUES, though I am the second owner and don't know of any issues prior to my purchase. During my time with it, I have only had to replace the 4X4 actuator ($500), headlight bulbs (typical), ball joints, and the rear U joint on the driveline. The motor has given me ZERO problems nor has the transmission. The interior has held up well with only a few small things like the coating on the dash peeling (has been very minimal). Only complaint is that the 5.3 litre is a little underpowered. I find that it frequently has to downshift when ascending in a canyon on a light gradient. However, this could be in part due to the age and milage on the motor. Overall I rate this vehicle as excellent!

As a first-time car buyer, I did extensive research as well as visit several dealerships in multiple different areas. Becks auto group stood out and by far gave the best overall experience without the hassle of a typical used car dealer. Sam and Doug made the process informative, transparent, and professional. I drove my car off their lot a month ago and could not be happier with its performance and use. There was some miscommunication with my trade in but nothing to diminish my overall experience. I recommend their services for anyone in the used car market.
Burdie was best vehicle I ever owned
The was my worked commuter the primary family car my son used it to get to college I miss that truck thats why I am trying to find another one we used this truck for everything until the acedent

The decision to buy from Korz Auto Farm came after an initial hesitation about navigating the car-buying process. Moe immediately put those worries to rest with his calm and knowledgeable guidance. He listened carefully to specific needs and helped narrow down the choices without any pressure. With every question answered clearly and honestly, the decision felt natural and stress-free. Moe’s approach turned what could have been a complicated process into a straightforward and rewarding experience.

Excellent customer service and quality vehicles for a
Excellent customer service and quality vehicles for a great price. I bought a used 2006 Chevrolet Silverado 1500 with only 51k miles at Fall Creek Motor Cars and it is in great condition inside and out. I am very happy with the truck. They have a really nice selection of Chevy trucks among other types of vehicles that are in great condition. They are priced competitively based on their condition and low mileage. You really get what you pay for, quality vehicles. Also, they have a free CARFAX history report on every vehicle they sell which you can view on their website. Thank you for the great service, I am a very happy customer!

I purchased a 2019 Grand Cherokee from Dee Motors, no pressure, very accommodating. Good price, great service. I will transact with them again. They did not have the car I was looking for on the lot, but found the unit I was looking for and had it on the lot in 3 days. Great service..
