i no this is abit off topic but instead of renovating a car to sell on , why not start off with old motor bikes ,
my father dose the really old stuff (cafe racers as the americans call it)
like triumph bonneville, norton commando , honda cb , triton etc
and ther is real money to be made in these if you sell over seas to like america or germany or to an enthusiast
on three of my fatehers build people from germany flew over to buy it test it and ship it back and he made a few grand on all them
key is to have no labour cost ( do it your self )
and no the market (no where to get good parts cheap)
but good luck in you ventures hope something works out for you's
