I don't quite understand what you mean by opportunity cost
Personally I have very little practical knowledge of cars, I know how to do a "full" service but that is about it really.![]()
Your point is?
What about getting some experiance first, and on a smaller scale with lower capital requirements, I'E buying secondhand UK cars and then selling on at a profit, after tidying them up, or buying them more cheaply in the first place via auction etc
