I'm kinda wondering what makes a person send an insulting reply to a fair question?
Most websites that follow a particular marque or engine are able to publish production figures for each year, and where the different models went in the world. For me, coming from the Supra community, it's useful to know where the sources of spare parts are. Also, once someone finds the production figures, the same datasource can usually provide the VIN or engine number decoding, so you can then know what year your motor was made. A nice bit of information to have when you want to confirm whether the seller is lying through his teeth to you when you're negotiating to buy a motor.
