A car I quite liked back in the 70's was the Alfa Romeo 1750.
Like most Alfa's of the period, absolute rot boxes, but georgeous engines.
I was offered one in the early 80's for pennies, totally shagged out and it would have needed a bare shell rebuild but at the time, they really just weren't worth it.
It would seem that restored examples have since become collectable though, probably largely due to rarity now..
someone's asking 30K for this one!!.
Still quite a pretty looking car.
