My C7 was manufactured in October 2013, and was owned by three different individuals before I bought it in May 2016. It was immaculate, and sold to me at 2,300 miles with a Certified Pre-Owned warranty. Now, almost three years later and 5+ years total, it has just over 26,000 miles.
I bought it because I had to have a Lime Rock Green Stingray, and I have no regrets. I haven’t had any warranty issues, except for the infotainment screen that went out. Based on what I’ve read about the A8 transmission, I’m happy to have the A6. But as an added sense of security, I did buy a GMEPP Platinum Extended warranty for an additional 60 months/50,000 miles from Dennis Fichtner.
I have purchased 19”/20” wheels and rear spoiler, so I essentially have the Z51 Appearance Package. I’ve also installed the Z51 sway bars; a Tony Mamo ported throttle body; a Vitesse throttle controller; a Z06 front grill and spoiler; a Mild 2 Wild switch; Oracle color-matched side marker lights; and CQuartz ceramic coating. I have also purchased Michelin All-Season 3+ tires as my daily set (I kept the base 18”/19” wheels and tires as a backup or track set).
I recently had to replace my battery for the first time. Other than that, this thing has been an angel. Plus, I now hold the title, free and clear. BTW....Did I mention I love this car?
