I have a 2017. I have no complaints. This is the first pony forum i've been on. If I remember, M6G is another forum.
Engineers are designing vehicles nowadays. When i can run a 2000 Honda on the track all day but the weaker version of a brand new Ford Performance car can't... there is something completely wrong with that.
Your opinion of good customer service is skewed in a terrible way. Because YOU are not sitting in in an unfortunate position, its easy for you to look at it in a brighter light.
The GT350 tech can run all day on track just as a 2000 Honda can. Lap times on the Honda will be slower after 10 min just as your mustang is. I fail to see the difference. I'd be will to wager the pulled timing on the tech 350 will still be faster than the fastest lap in your 2000 Honda street car.
