I recently bought a car from them. They are really honest guys, and the car I purchased is a 2018 Hyundai that is in excellent condition. If you want to buy your next car, I would highly recommend going here because the procedure is really simple and everyone you deal with is quite nice. Definitely 5 Stars:
2015 GMC Sierra 1500 review
SLT with most options. Purchased at 127k. Currently have 141k after 17 months of ownership. The tranny that came with it was not original. I have had to replace ball joints, a/c condenser, brakes, wheels, radiator, a battery and a starter. Can't complain at this mileage. This is one of the quietest vehicles I have owned (that includes Audi A8's) and it's shod with Cooper Discover AT3's that chomp through snow like my Toro snow thrower. I also replaced the stock halogen bulbs with LED's and what a difference! The interior is comfortable, and I did replace the drivers seat bottom cushion. The nav system sucks, it's not very intuitive and it isn't very good at mapping the best route. Besides, I use my sedan for long trips. Phone integration is a breeze. Radio surprisingly decent. Everything works as it should. It's easy to pop the kayaks in the bed and the ebikes on a carrier and head out for the weekend. When moving stuff, I have the 80" bed so I can fit loads of stuff under the hard tonneau cover. The interior still has NO squeaks or rattles. Amazing. The heated seats are slow to heat, and the heated wheel is slow to warm up. But this thing is such a beast in the snow and rain I don't want to drive anything else! All in all a very reliable, well-built, and for the genre a good-looking vehicle. People tell me all the time what a nice looking truck I have. It's stock. Thanks, GMC.

Berkenkotter Motors Castle Rock review
We purchased our vehicle from Berkenkotter Motors and we couldn't be happier. We came from Brush in search of a 4 runner and the experience was well worth the trip. Lucas and Dan were very honest, helpful and treated us with respect. They were easy to work with and made us comfortable with our purchase. They made the buying process stress-free and they ensured everything was handled smoothly. I highly recommend them. Thank you so much guys! We definitely recommend your dealership and look forward to working with you more in the future!
2015 GMC Sierra 1500 review
We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

I had a great experience with this dealership. The dealership has a small home town feel but with a large inventory. Sales professional Michael Fresquez was friendly, able to answer questions promptly and all without pressure of making the sale. I would certainly consider buyers my from them again. It was a pleasure working with Michael on finalizing the deal on my Ram 3500 Limited purchase and LOVE IT!!!

I have been looking for a Subaru Baja fora while now and I finally did at carmax in salt lake. I was three hours away and couldn't get out there quickly so they held the car for me. FOR A WEEK. They had people come in and was wanting it.But they still held it. I wish they would negotiate on the price. But I got it at a good price. The car was in top shape and the interior is awesome. Thanks carmax.

Lakeside Auto Brokers review
I recently purchased a car from Lakeside Auto Brokers, and the experience was nothing short of exceptional. My salesman, Ed, was truly outstanding—by far the best I've dealt with in my 55 years. Despite my recent Chapter 13 bankruptcy, Ed worked tirelessly to secure financing at a fair rate, and his dedication made all the difference. On top of that, the vehicle was priced very competitively. I wholeheartedly recommend Lakeside Auto Brokers 100%—if you want to be well taken care of, ask for Ed.
