Got ya all beat age-wise - age 83 - and I still refuse to grow up. Bought my first car in 1948 at age 13 - a 1937 Chev Master Deluxe Coupe (5-window) with a rumble seat and continental kit as part of the factory package. It had been owned by a little old lady who drove it all through WWII with no maintenance. The stove bolt 6 burned a quart of oil every 30 miles. That’s how I learned to fix everything automotive as well as do body and paint.
I went on to become an Advanced Engineer at FoMoCo in Dearborn during the 50s and then the proverbial Rocket Scientist in the 60s.
After retiring 22 years ago, I finally built my adult toy store complete with a 2-column, asymmetric hoist so I don’t have to crawl under anymore. The toy store currently contains my '48 Plymouth Coupe which I built and raced in the La Carrera Panamericana 2000 mile open road race for many years; my '57 T-Bird, a 78 El Camino, an 83 El Camino, a 2007 Corvette and a 14 Lincoln MKX daily driver. My 66 Mustang rag top is in my son’s garage in Houston along with my 74 Norton 850 Commando Interstate on which I toured Europe in 1974.
I don’t work as quickly as I used to be able to do, but I think I’m still a pretty good wrench and my love for cars is as strong as ever. Fortunately, my Bucket List is still as long as my arm and everyone knows you can’t check-out until you finish your list so I think I’m good to go for many more years.
