At the risk of killing off yet another thread, this reminds me of my brother's (ex) father-in-law, who was a legend in his own mind. He had all the answers, on any topic you happened discuss, although those answers were frequently incorrect. He owned a '29 Packard four door sedan, with a straight eight, unrestored survivor. At the time, I was 25, doing the chassis work on my '40 coupe, and had just rebuilt the flathead with polished Evans heads and manifold -- you know how it looked. Took him out to the garage to show it to him, and his response was "oh nice, but isn't it kind of an abortion?"
Later, he complained that he wasn't able to take his Packard out as much as he liked because he wasn't able to wash it anymore, and didn't want to risk it at a car wash. Told him I'd be more than happy to wash it for him. So he says come on over on Saturday and you can wash it and then we'll take it for a spin. I was delighted at the opportunity to go for a drive in his Packard, and eagerly headed over there. Washed it carefully for him, and when it was chamoised off, he says "Ok, let's run it over to the gas station and put some air in the tires. Here's the keys." I was dumbfounded! I never dreamt he would let me drive his car, and had also never driven a crash box at that time. So, we climbed in, and although I knew the theory of double clutching, the practice took more than a few crunches! I was of course horrified to be grinding away at his transmission, but he just sloughed off my protests. Anyway, I got the hang of it finally, and thoroughly enjoyed the experience. At that time (1985), people would wave at you when you drove down the street in a vintage car. I felt like Lindbergh in the ticker-tape parade, except that I was doing the driving.
Anyway, when we got back to his house, I handed him the keys, shook his hand, looked him in the eye and thanked him for a once-in-lifetime experience.
His response? "Arrg..harumph!"
It was indeed a once-in-a-lifetime experience, but I am still thankful to him for it.
