My dad and I were thinking about getting a 1960 Caddilac Convertible and restoring it. We wanted it since ages but we never found the right one for our budget. My dad tought that we could get one from a junkyard or get a cheap not so great car then restore it. We dont know anything about restoring a car and would like a shop to do it for us. Where could I find a shop and how much would it cost to restore it? (By shop I mean like to shops on tv were they restore cars but it doesnt neccessarly have to be the one on the tv)
