What is a 1985 cj5 jeep worth?

It really depends on a lot of factors. Such as engine size, transmission type, overall appearance mileage, and lots of other things. You can look up values at nadaguides.com, just search under classics. Also take into consideration if it is a daily driver the value will be lower than a show vehicle. Also another way to get a good average value is to see what they are selling for in your area, just compare similar models and you should be fine. A good price for a decent 1985 CJ5 should be around $3000, but it can be much more or less. Good luck with your hunt for a Jeep.
