I owned a 1969 MGB for 12 years, and a '74 for a few years before that. So I had a bit of experience getting stranded. :O
The times I had to get a tow included: broken U-joints (twice) where the driveshaft separated from the transmission; blown head gasket; and a burnt exhaust valve.
Looking back I'm amazed I didn't get stranded more often. In the '69 MG, I had a dead battery maybe half a dozen times, but always had jumper cables, a jump-starting battery pack, and/or a battery charger. Leaks developed in the radiator, but never large enough to fail catastrophically before I could re-solder or replace it. The fuel pump occasionally died, but I could always get it working again by whacking it with a hammer until I had time to replace it.
The MG also had genuine wire wheels that required tubes (like a bicycle), and I got 13 flat tires in 12 years. Thirteen! But most were overnight flats and for the ones that weren't, I just quickly put the spare tire on.
One year in college, the seal in the slave cylinder for the clutch was leaking, and one night when I was going to drive home, the clutch pedal just fell to the floor. So there I was underneath the car in the college parking lot at around midnight bleeding the clutch, using a can of beans (after I ate the beans
) to catch the clutch fluid.
The most epic trip I had was with the same MGB in July 2006. I had already moved to Colorado from California a year prior, and it was time for me to move the car from a friend's place in CA to my new home in CO. During that 1100-mile trip I got three flat tires (fortunately, two of them occurred next to a Big O Tire shop in Reno) and the car was stalling out on I-80 near Salt Lake City. I got the car going again after swapping the spark plug wires for some old ones, but the car only ran on three (out of four) cylinders for the rest of the journey.
I was then so anxious to just get the car home that the only sleep I got was a catnap in the car in Wyoming, and somehow was back home in CO after only 25 hours despite the problems. All without needing a tow.
But probably unsurprising to say, I decided to sell the car shortly after that. :O
