I had an amazing experience working with Gary and Jorge
I had an amazing experience working with Gary and Jorge when purchasing my new F-150. They went above and beyond to make sure I got the best deal possible and took the time to answer all of my questions. The entire process was smooth, stress-free, and professional from start to finish. I truly appreciate their honesty, patience, and dedication to helping me find the perfect truck. I highly recommend them to anyone looking for a new vehicle!
best in class
My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

Terrific experience with Aidan!
Terrific experience with Aidan! He was not like other used car salesmen. He was professional but also personable while listening to my needs and wasn’t the least bit pushy.
Better than my old truck
The truck has more features than I need. It is quiet and comfortable. it has plenty of power to pull a work trailer. Overall a nice truck

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.

I hat great difficulty connecting home link to my garage
I hat great difficulty connecting home link to my garage openers on my new gv70. Anthony (service manager) at Lakeland Florida Genesis made a special trip to my home and hooked us up. This example of service and organizational culture is a rare commodity. Having managed 100’s during my career I understand how difficult it is to achieve this level of commitment. Cheers!
