I turned my grey market Range Rover upside down, in the middle of the night, on an unmarked dirt road.
I was driving down that dirt road and came to an unmarked 90-degree turn — of course I was going too fast, and though I made it around the turn, I managed to catch a tire on the edge of the road, and slowly turned the truck over, where it landed on its roof. The door was stuck, so I scrambled through and out the back. Amazingly, the truck was still running. I decided that with the electric fuel pump, it was probably a good idea to shut it off, so I climbed back in, found the ignition, and stopped the car. Climbed back out. Walked down the road, found a farmer who helped me get it back on the wheels.
At this point I should have removed the spark plugs and blown out the oil, but I didn’t know that at the time. So I started it up and drove it home.
Then (with the help of the local farmer) turned it back over, sawed the top off, and had a full roll cage built. Drove it for a while. Then on the way across Utah in the middle of the night it threw a piston through the bottom of the pan. Second craziest reason to stop the car.
Sold the carcass for parts.
The most impressive thing I ever did with my Range Rover, at least the most memorable.
