This is an attractive and enjoyable vehicle.
I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.

great service
I bought a car from Springs Auto Group last month. Shawn and the group at Springs were very professional, polite and not high pressure at all. The process was smooth and easy. I would definitely buy there again.

Grand Valley Auto Sales - Lakewood review
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!

Planet Hyundai review
Planet Hyundai is very patient and very friendly.
Mick Hasley and the team are patient and friendly. When they say they will call back they do, and they are not in a rush, they listen to what you need. I had a 100+ questions as i had not purchased a new car in many years. I was searching for just the right car for my wife, and they listened to what I wanted, and not what they had in stock. Their online chat service is pretty good too if I have a question I think of, I ask the chat and it gets to the rep and they replied. Honest about prices as well.

Awesome buying experience
Very good buying experience. We purchased a BMW with the help of Phil. Both Phil and the rest of the staff were always very friendly throughout the buying process and we never felt pressured to buy the vehicle. We were able to test drive the car by ourself and more than one time before buying.

Rafeal was my contact there and he was great.
Rafeal was my contact there and he was great. He went above and beyond to communicate share photos and video and was very transparent. As a matter of fact the whole process and everyone was easy to work with. Not the dealer where sale and sale manager go back and forth to do some crazy negotiating. Open transparent and fair dealing. Rafeal was an advocate throughout and in and out with anew car well less than an hr after trade in paperwork
