Watch: Is That GM Pres Mark Reuss in this C8 Prototype? by Evan Williams March 7, 2019 Share Comments The latest C8 sighting puts a big GM exec in the passenger seat. A Realtor and YouTuber looks to have spotted GM President Mark Reuss riding shotgun in a mid-engine Corvette prototype. Or at least we’re pretty sure that’s him in the car. There wasn’t just one prototype here, there were actually six of them in the convoy. Some with an upright spoiler and some with no spoiler at all. There are a couple of different wheel designs on display as well. George Kenner, the capturer of the cars spends some time explaining how he happened to see the cars, so if you just want to see the cars then skip ahead to about the three-minute mark. Then watch and get some great visuals of the camouflaged and covered prototype Vettes.
