I took my GT to Autonation Ford Frisco in March 2018. Beforehand, I spoke to the service manager and he assured me the car would be in good hands with their master mechanic. I dropped the car off and met the whole team. They did a great job and even did an oil change. I usually get my oil changed at Boardwalk Ferrari in Plano, by Chris, who does all my work on the GT.
Hope to see you out on the roads! Let me know if you ever want to get the cars together. Offer extended to all other Dallas area GTs too!
