Archaic?  Belts are just cheaper for the manufacturer, and they add to the
maintenance for which the dealer can charge.

Actually BMW's M20 small 6 (in use from about 1977 through the early 90's),
the M40 4, and at least one of their diesels, the M21 6, use belts.  The M10
single cam 4 and M30 single cam 6 use chains, and as far as I know all the
later inline 6's, V8's and V12's use chains, at least up through 2000.
Again, archaic?  Think what you want, but BMW's marketing hype doesn't stop
their engineers from being talented people who design very good engines.

Mine's not, the Alfa would be lonely in the garage without it!
