If that guy lived nearby and was amiable, I would volunteer to work at such a garage. As a teen, I worked with a guy like that in the '70s who always had older foreign cars around. He was born in Bolivia, worked at a meat packing company as a chemist, and traded 55-57 Ford Thunderbirds (mainly) along with working on cars. Ah, the days of my youth spent tinkering on cars.
Not a Harley fan, some Japanese bikes are ok but the older British and German bikes spark my interest. I want a Triumph Bonneville - but not a new one. Instead, one of the older bikes. I like working on motorcycles more than riding them - at least riding on the road.
