My experience at Ricart Used Cars on Billingsley was one
My experience at Ricart Used Cars on Billingsley was one of the best car buying experiences I’ve ever had. From the moment I arrived, I felt welcomed by the sales team. The entire process was smooth and hassle free, with no pressure in my decision. A big thank you to James and Andre they were incredibly welcoming and great to work with. Ricart Used Cars has earned a customer for life!

This was absolutely the best experience I have ever had
This was absolutely the best experience I have ever had at an automobile dealership. The Salesman Bryan Struzynski was terrific to work with and Ray Wojcik the Business Manager was as well. We walked away with a great experience and a new truck.
Never had one. Always wanted one and love it.
I love my Denali. Beautiful truck inside out. When I drive down the road all heads turn. I couldn't have made a better choice. That's Cortez for you good service.

Oil and Filter change, Parts, Service, Excellent Staff,
Oil and Filter change, Parts, Service, Excellent Staff, What else could you want. There is a dealer only 2 miles from my home but I choose to drive 34 miles and know the job is done right.
Early to tell truck has less than 100 miles
Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.
