Of course, you're hoisting yourself with your own petard there.  The ILEA page you cite appears to be simply reporting the results of a 1998 Carnegie Mellon study.  That isn't exactly "citing - and reading - the original source."  

Frankly, it looks as though the difference is largely down to the amount that the vehicle is driven and the Heidelberg research including the eventual disposal, which the Carnegie Mellon research left out.  Europeans drive less so that manufacture is a bigger percentage, Americans drive more so manufacture is a smaller percentage.

No, it's much more than mileage; if you assume an 81,000 mile lifespan the manufacturing fraction only rises to ~20%.  Something else is needed to account for another multiplier of roughly 1.6.

On the mileage thing brand new totaled vehicle wrecks bring the average down, as do any wrecks.
