The service manager was outstanding.
The service manager was outstanding. He was involved in every aspect of my car repair. My issue was very difficult to diagnose. I observed him interacting positively with employees. I saw him doing manual labor, which you usually do not see. I was greeted positively from the moment I arrived. This is in contrast to the negative experience at AutoNation Chevrolet Pembroke Pines down the street from me. I know a positive business from the moment I walk in. I observe all employees including the amount of time spent with customers or just in the customer area. Happy employees are going to give customers a better experience.
Beautiful truck
I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Excellent service.
Honestly I was starting to feel Very overwhelmed for a time during the price/payment discussions, but Chris and his team were very helpful and willing to work with me and I ended up with a 2019 Ford Escape that I feel very comfortable in.
Best truck I ever owned
Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

Thanks John Lewis for a happy trucker
Looked at a truck we were interested in on a Sunday morning with John Lewis and he made the sale and us driving it off the lot in the same day!! Great service as always
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.

Quick response to the initial online inquiry.
Quick response to the initial online inquiry. Appointment scheduled for test drive over the weekend. The dealership even kept the car for me to test drive even though a few other customers inquired about the vehicle prior to my test drive appointment. Experience at the dealership was quick and smooth. Met a couple of good individuals during the process.

2010 Mustang GT500
I bought a 2010 Mustang GT500 from Tyler at Classic Motor Cars. I was a bit nervous because I was buying a car without seeing it first. Tyler made me feel much better about it. After buying it, Tyler picked me up at the airport and drove me to the dealer to pick up the car. Everything about the process was terrific. The car was as nice as I was told and he even sent pictures of the 2 flaws on the car before I bought it. It was a great experience and a great dealership.

They made sure every step was smooth, all questions were answered. Also, the vehicle was built (26 Tahoe) and completed early, less than 3 months. Completing the deal took under 4 hours and I drove off with the vehicle.
