For 30 years I have wanted one of these cars and finally found one in good shape that I could afford. The previous owner (I think he said he was the third) had the three small rust spots in the lower quarters cut out and new metal put in. He then had the car repainted and clearcoated the original color which he called patina silver. He had the tranny rebuilt because it was leaking at 2 or 3 of the seals. AND the car has 57,000 original miles on it. I am in heaven. I have done alot to it myself but it has been inexpensive so far (for the first time in my life). The top would go up and down but at the halfway point it would lurch. I started playing with it and found numerous loose bolts on the frame. Tightened them up and she goes up and down like new. I cleaned the carb and reset the float so now the four barrels open when you step on it. I changed the oil and rear fluid and I just put on a new power steering pump and valve cover gaskets because they were leaking. Looks like a new radiator in it as well as new belts and hoses. Since this is my first time fixing up a car what other key elements should I be checking? Or does anyone know of certain aspects of the 70 deville convertible I should look out for?
