Ranger boat model ID?????

[CN Spots]

Anybody have any idea as to what the model numbers on Rangers mean?? I'm sure there's a code or something: (add the first digit to the third digit, divide by the second digit, multiply by the trolling motor thrust and subtract tow vehicle year etc, etc) I'm confrused. <br /><br />482VS?<br />390V?<br />373V?<br />R93?<br /><br /><br />spots?
