I have a 74 maverick 4 Door, 63,000 original miles. Interior, spotless, Exterior excellent..Has a 250 6cyl and c-4 Automatic Trans. No Air. It has been in a garage it's whole life. I do not have any idea on a value..HELP !
While many 4 doors are very solid, nice cars. They do not command the prices that a cherry 2 door will. Price will vary greatly in different parts of the USA - higher in the rust belts and lower in the west. Put some pictures up and we can tell more - but anything here is just going to be a guess.
Without pictures it is hard to say. If its in excellent condition, inside and out like I gather from your posting. Depending on area you market it to.
Also depends on what you want the value for. Are you wanting a value for insurance purposes? Are you wanting to sell the vehicle? The two numbers will be different.
