A big part, I think, is differing European attitudes towards maintenance. If there's a bit of coating damage and a rust spot somewhere detected by a mechanic in the US, everyone involved is likely to shrug and not bother with any remediation. The customer doesn't want to pay to prevent a problem that will manifest in years, and there's more lucrative work the mechanic could be doing.
