I have a C6 and I was terrified while descending Mount Baldy on black ice and snow at night. I was praying for a turnout where I could stop in time. I had people beeping their horns behind me as I skated down the highway. My fault for leaving too late with a severe temperature drop. Made it though without a scratch. Stayed up all night cleaning my baby too.
I must say though that there is a car that is worse.
I once had a '69 Charger R/T w/440 6bbl. (Holley mechanical secondary type, not vacuum). That car was so front heavy and rear light that it would not even drive without weight in the trunk. I had to put a box of tools in it just to get to the fire dept to get sand bags.
My GF's car was my best experience. A WRX Wagon (Subaru) Excellent cornering in snow believe it or not. She would take these corners and I would be going 'Oh my God!' and bracing myself. She would look over and go, "What? what is wrong with you?" She's so used to it I guess.
Lastly and most importantly:
A lesson that should have been well known a long time ago.
Never question mother.
Mother is ALWAYS right.
