I'm what you'd call a below average wage earner and I'm looking to buy a Ford Cortina of the mid to late 70's early 80's. The model with the very curved rear arches that had me watching them on the roads as a boy. I would be looking for one without rust because I understand the expense of dealing with that and a sound engine. Also would today's good garages have issues with minor repairs, parts for a car of its age. I believe these cars came in 1.6, 2.0 and 3.0 litre engines. Who might you suggest as the best or most reliable source for one of these models?
