Mechanical "skill" is not a "talent".

There is no reason you cannot learn some basics.

There is also nothing intrinsically complex about most of these cars.

The newest car I currently own is a 1967 Mustang. I don't have a problem driving it every day. It's simple and fairly reliable, esp. when I replace all the rubber bits that have dry rotted over the years.

Once a car is sorted out, classic or kit, they shouldn't be "money pits" unless you let them sit for long periods of time, or abuse them.
