Willie was great to work with and made the buying process
Willie was great to work with and made the buying process very efficient. He was also very knowledgeable about the truck and did a nice tutorial to set it up and show me the features. Did the negotiation through email and when I came in to faint the paperwork I was only there for an hour and fifteen minutes total before driving off! The usual upsell of extras during the finance process but they weren?t too pushy about it.

Amazing!
Amazing! Always such great service. The staff is wonderful, so friendly and kind. I went for an oil change and they were so quick and efficient.
Truck is a Solid vehicle overall.
Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.

I took my little Buick Encore there because the check engine light was on. My mechanics name was Nico. He was very informative and responsive. Let me know what was going on through the whole process. These people are great! Reasonably priced. I will absolutely go back there.
Great Diesel truck when emission sensors work
Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

Kevin did a great job!
Kevin did a great job! We went in looking for a car that showed on the website that it was being delivered that week. He helped look up the vehicle and then also gave us other options for the same model that were already on the lot. We had a limited budget and he found a us a great option for a vehicle that was a lender that had been used by dealership. It had only a couple thousand miles and was in perfect condition. The financing agent was also very nice and found us a bank that would give us the lowest intrest rate for the loan. Kevin helped us set up our Chevrolet app and got us points for the purchase and the Onstar welcome call. They washed the car for us and filled up the gas tank. He went over the features in the car and let us do a test drive. I left extremely happy and love my new car!!
My Favorite Truck
Lane Departure saved me on a few long trips. Seats are extremely comfortable. Fifth Wheel Prep made it extremely easy for my hitch installation. Amazing Sound System

I have purchased a number of vehicles from this location under different ownership. The one good constant has been the service department and the service tech Dave Singh. Ask for Dave he will not let you down.

Great Trucks! Owned quite a few and they never let me down and seem to hold their value. I will keep buying them for as long as I can.

My wonderful car buying experience
I was very pleased with the vehicle I was able to purchase at Grand Valley Auto Lakewood! I had less than perfect credit after being left carless in my divorce. My friends had recently purchased a car from Mike and Kelley and they assured me I would be treated honestly and fairly. I was very skeptical due to the fact that I had recently been taken advantage of on the purchase of my new TV. They listened to my wants and needs and I left in a car that I both loved and knew would do the job. I would definitely recommend and return for my next vehicle purchase!

Purchasing a car here at Family Trucks & Vans was the most pleasant, efficient experience! Our salesman, Juan, streamlined the process and scored us a great deal. I highly recommend checking out their line of vans and trucks. Great selection!
An overall nice truck but for a person at my size(5,11)
An overall nice truck but for a person at my size(5,11) the mirrors and posts really block the view. My tinted windows really amplify the problem. The hood also takes a bit of room for a short person. Its a comfortable ride and works well in my line of work in excavation. The sound muffler in the hood makes you think something is wrong but apparently its not.

Greg Wolaver was a great help in regards to my long distance purchase of a used Jeep Commander. He was up front during the whole process and greatly assisted in the shipping process. I haven’t gotten my vehicle yet but if it’s half as good as he stated it will be a great purchase.
I have had to of these before and I drive the xxxx
Just what I was looking for and the price was right. The color was the same as the truck I traded in. We have purchased a bumper pull camper and now mountain passes will feel like flat roads!!

I was here at the dealership a few months ago and I traded in my 2010 challenger on a 2014 challenger. The new one I purchased was an absolute gem. It only had about 600 miles on it. I thought “no way will this get approved” I’ll have to drive two hours back home without the new vehicle. Well I am pleased that I had Vincent and Kurt to help every step of the way. Between the two, they got me the best deal possible and I got exactly what I wanted. Never any pressure at all from anyone. The whole team there was exceptional to work with. I couldn’t have asked for a better car buying experience. Thank you to everyone. I definitely recommend going to Omeara. I will for sure be going back when I need to purchase another vehicle.
