Haven't read through the thread, but thought I'd share this one:
Back in the late '90s I had a customer who was an investment banker who'd bought a 40 series because it fit the outdoorman image he wanted to project. The craze hadn't started yet, and he'd got a V8 powered, SM420, front disc converted '71 for about 5K that I was slowly debugging for him. I'm just going to say that he was not mechanically inclined.
He told me he was a hunter and belonged to a club that had private hunting properties around the country. He invited me to join him on a trip to one in Northern California to hunt wild boar. Sounded interesting and different, so we set it up. He arrived at my shop around 7pm and we drove through the night, arriving in Laytonville around 7am.
The hunting was a dud. We only saw deer, and they practically came right up to us since it wasn't deer season yet. We decided to go for a scenic drive, and on the drive, the engine developed a miss, and I told him the engine was only running on 7 cylinders. He could not hear or feel the problem. It was drizzling, so I waited until we got to a gas station with an awning to investigate.
When I opened the hood, one of the spark plug wires was laying on the frame! He was SO happy that his mechanic was along! I was about equally dismayed that he couldn't tell there was a problem. Plugged the wire back in and proceeded without further incident.
On the trip home, we made good use of the V8 and hauled ass down interstate 5 through the Central Valley, where facilities are few and far between. Somewhere around King City we stopped for gas and when we jumped back in the truck, no click, no starter. I opened the hood to check the wiring and everything looked ok. Typical V8/ heat sink issue.
At this point he comes unglued, spouting off that we're in the middle of redneck rural America, and we're going to get screwed having a Toyota, blah, blah, blah. I told him to shut up and give me his hat. He looked at me quizzically, so I asked him again, making sure he understood that I was serious.
Then I hit him with his own hat, like the Skipper used to hit Gilligan, told him it was a stick shift, and we could push start the truck!
He didn't believe me!
He wasn't much help pushing the truck, and was a little heavy/ slow hopping into the rolling truck. But on the 3rd try, we had enough momentum to pop it in 3rd gear.
He grinned at me sheepishly and said if I hadn't been there, he would have paid $300 to have the truck towed back to LA.
