[s-cars] Hey guys, your cars don't exist!

[Dave Forgie]

The problem starts with the fact that there were no S2's imported to the US 
or Canada.  The next problem is the electronic parts catalogue (ETKA) (aka 
Family Album (FA)) that the dealer would be using doesn't list the S4 per se. 
They are 100's with the 20vt  AAN engine option, etc. 

Then as far as the head gasket, the S4 AAN paper and metal head gaskets 
are no longer available.  However, the S6 AAN all metal head gaskets are 
available. (Which is good).

You need a friend with a FA to "share".
