Craige was great and squared us away in our 2026 Rogue. We traded in our car because of expensive repairs and are happy with our purchase!

Call to about a concern with my check engine light. Was done fast an efficiently was a power train issue and was fixed correctly. Truck is running fine.

2021 GMC Sierra 2500 AT4 review

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.

Troncalli Chrysler Dodge Jeep RAM review

Absolutely the quickest and most stress-free vehicle

Absolutely the quickest and most stress-free vehicle purchase I have ever made! Everything went smoothly and the deal was processed as promised. Our salesperson, a young man named C.J., was knowledgeable and easily surpassed the service I’ve received at BMW, Mercedes-Benz, and other quality dealerships. He is an honest, no-nonsense, no pressure, type of guy and a great representation for Troncalli. I can’t say enough about this young man and the pleasant experience we had while purchasing our new car. Kudos to his parents who definitely raised him well. Wish I could give him more than 5 stars! The whole team was friendly and welcoming. I definitely recommend and will undoubtedly return when we are in the market again for a vehicle. I wouldn’t be at all surprised if CJ is promoted to manager by then.
