Yearly mods

[gagala]

Is there a place where I could see a summary of the changes/modifications that were made to each ARGO model by year.

For example, if I take the ARGO CONQUEST, what was changed on it every year ( by year ) since its introduction.

I am considering buying a used ARGO and that would be very helpful in helping me determine if a certain yea model is worth more than another.

Simply, no.
Looking at the parts manuals by serial number breaks is about the only way to accomplish what you are after.
