Very true, however, retooling for finishing the cars would still have had
to been done.
I imagine (not that I've had experience in designing equipment for
outdoor exposure,
just inside industrial with NEMA explosion proof ratings and submarine
reactors fittings)
that the retooling for production level finishing probabably would not
have been feasible for
a car that was being phased out in 2 yrs, so I imagine that is why Audi
didn't galvanize the
85-87 type '85's, which I do know this to be true. I did have an 84, but
my best friend's 85
and another friend's 87 weren't galvanized. Still, for whatever reason,
the cars seemed
remarkable rust resistant to the metal worm, though surface rust was an
issue. They certainly
were much bettter fighting corrosion than BMW's and even VW's of the
time, although the A2
series of Golf/Jetta/GTi's seemed better than their A1
(Rabbit/Scirocco/Jetta) predecessors in
that respect.
