[s-cars] AAN 20VT in 4000CS

[Vincent Frégeac]

You're true. I should have checked the Audiworld Historical database
first. It seems the anti-corrosion process appears with the B3 only. I'm
still puzzled how the hood and left fender of my '85 CGT have resist 5
quebec's winter with no more damage. It seems Audi gods were good to me
at this time... and they changed their mind when I left the CGT go in a
scrap yard. When I bought a Mazda to replace the CGT, they should have
been really pissed off. I understand their reaction :(

Chalk it up to luck?  Unfortunately NONE of the type 85's were ever
galvanized.  I _think_ Audi's first galvanized car was in 1984 with the
introduction of the type 44 platform.

The type 85 was introduced in 1981, and at that point Audi probably
hadn't considered galvanizing quite yet so it created the tooling for
the platform without the necessary features required for the galvanizing
process (such as rolling the edges of body panels).  Audi probably
decided not to retool the platform for galvanization since the type 85
was phased out in 1987 anyway, at which point the type 89 came on the
scene with a lot of advancements that never hit the earlier platforms..
galvanization being one of them.
