James Wood Decatur
Misty was great as was Rusty. I?ve been trading with Rusty for over 30 years at James Wood Motors. Misty came in on her day off to deliver my truck and took time to explain all of the new features. This is why I drove 3 hours each way to do business with James Wood. James Wood Motors is the absolute BEST dealer in Texas.

Ewing Buick GMC review
I hate singing the service for an intermittent issue
I hate singing the service for an intermittent issue likely caused by a computer chip, on board computer or software but it a serious issue when the Adaptive Cruise control just locks the brakes up at cruising speeds over 55 MPH. I am hopeful they will eventually figure out the issue. This time I requested they just deactivate Adaptive Cruise as I?m worried about serious injury. The last time the brakes locked up out of the blue, I almost lost control of the vehicle and it slide sideways almost flipping at 70 MPH.
