I can answer if you can answer my question- My neighbor has a car he wants to sell. It is a Chevrolet. It has 4 wheels.
WAY too many variables to answer your question, or mine. Prices on these are measured in thousands of $$$, and will be driven by EXACT model, EXACT condition, etc. Will need a HANDS ON appraisal by someone that knows old Colts- and the difference between the models.
