Best Car Buying Experience EVER
I have bought a lot of vehicles in my life time but this was by far the easiest and most pleasurable car buying experience I have ever had. I sent an email to the dealership around 1:45pm to inquire about a car, drove to the dealership at 5:00pm and drove home at 7:30pm that same day. Ricky in sales was amazing, easy to deal with, I told him what I needed and he took care of it without a bat of an eye!! I will refer anyone to this dealership and specifically to Ricky Pim. Thank you guys!! you are the best! PS - Finance guy, equally as great!! Jersey!

Happy customer
The sales team was very prompt on getting back to us when we inquired about our vehicle. They were also very informative on the product and were able to answer whatever questions we had for them. Once we were to the point of agreement on the price of the vehicle they were always helpful with the rest of the sale all the way thru the sales contract. This was very helpful as we are in another state and everything was over the phone and emails. Thanks again, The Woodruff’s

Amazing car buying experience!!!
By far the least amount of time spent purchasing a vehicle. We knew the numbers, and got all questions answered in a matter of minutes. They brought the car closer to us and had all paperwork ready to go. It only took 10 minutes and we were on the road in our new car. Well done!

These guys were absolutely great and very easy to work
These guys were absolutely great and very easy to work with. There wasn’t any pressure and no pushy salesmen. We came over to buy a car from another dealership and things didn’t work out and we didn’t want to leave empty handed. These guys had us in a new car within an hour and a half !

I never experienced any issues with Jensen?
I never experienced any issues with Jensen?s Motors service Department. That?s why I keep driving an hour one way every time to get my car serviced because I know it will be done right. I have been buying and servicing my cars there for over 40 years.

Friendly, hard working staff.
Friendly, hard working staff. Kline was professional and personable. Kline is the MAN! John was also very friendly and flexed with his ability to get me financing. Niko was also a pleasure to deal with. Overall a seamless and painless deal. We never felt pressured but we did feel welcomed. Everyone was very friendly. We would gladly make the drive up from Brighton, CO again.
