Come on, be honest. Your response of "Really,if they dont keep up with year models why would they go thru the trouble of putting serial numbers on all of them?" comes off as a challenge to Len's statement that the Japanese did not track model years. My comment was in response to that--AND I answered your question about why they put serial numbers on them. Don't ask a question if you're not prepared to accept the answer. Your last response is the one that gets personal. My response was serious and sincere....if you don't accept the information you get here in response to your question, contact the manufacturer.
Ask away....in no way did I criticize your asking a question. I did suggest you consider a different source (the OEM) if you don't believe what you're told here. However, if it suits you better I will be glad to put an "ignore" by your name so I don't see or respond to any more of your posts. This is also serious and sincere.......just let me know.
