My dear departed older brother was a brilliant Automobile Master Mechanic, very talented overall mechanical technician and one Helluva sports car driver, motorcycle rider and airplane pilot. He owned a thriving precision tune shop in a very affluent urban area that worked on everything from Ferrari's, Lamborghini's, Mazerati's, Jag's, Aston Martin's, BMW's, Mercedes', etc. to the various Japanese high performance models to Classic Vintage Marques. His Hobby on-the-side was helping with the engine/transmission work for folks who were restoring Vintage airplanes and motorcycles...Anytime our elder brother was having trouble with one of the tractors, pickups or hay cutting/bailing machines on his ranch he'd go out and fix it for him.
He owned a favorite personal toy in each of his three passions...sports cars, motorcycles and airplanes. His choice for his personal sports Car was a Mazda Miata.

EDIT PS: At the risk of sounding too "forward"...Your Mrs. sounds like my kinda gal.
EDIT PPS: When my brother was 14 years old he rebuilt a '47 Flathead V8--including hand grinding the valves--all on his own.
