Not Chevy stories, but I hope you will find it amusing anyway (if you can understand my "Swenglish" language).

Many years ago I was at the Mc D drive-through. You have to stop at two places, the first to pay, and the second to pick up the food. The arabs in the rice-burner in front of me didn't get close enough to the car in front of them while waiting for their food, they just stayed where they already were, making it impossible for me to get to the cashier to pay. I honked, and they didn't get my message, so I pushed them away with my old Volvo! There were four of them, but they didn't dare to go out and fight! They just stayed in their car while I paid, that's pretty humiliating for them.
At a crossing of a road, the car in front of me didn't see some guy crossing the street at first, so he had to step on the brakes. Since I was second in line I had to do it as well, so the rice-burner after me crashed right into my rear end. My trailer hitch gave him a hole the size of a football in the front, and nothing happened to my Volvo.
