I've tried the VIN decoder from these pages and have run into an anomaly. either the VIN decoder is wrong, or I don't know the ramifications of what an S is, or the dealers are stupid/lying.
when I put in this VIN: 3VW447AU5JM254864. it comes up as

2018 Volkswagen Golf GTI 2.0T S DSG

VIN: 3VW447AU5JM254864
it was advertised as:

2018 Volkswagen Golf GTI 2.0T Autobahn 4-Door FWD

Price includes $433 delivery to Olympic Valley, CA

$22,367

What am I looking at?
