Welcome aboard!
Not to get technical or anything but a "Bavarian" car would probably be a BMW since they are based in Munich in the state of Bavaria. Mercedes, on the other hand, is based Stuttgart in the state of Baden-Württemberg.I'm keen to get into my first Bavarian after being an owner of predominantly Australian made sports sedans.
Yes it's a HSV Senator, a 4 door sedan. Gen 3 6.2L Chev motor putting out 317KW. The HSV Monaro (a two door coupe) was re-badged for the US market as the GTOP.S. Nice Holden...that is a Holden HSV, right? If I remember correctly, the late model Pontiac GTO that was sold in the US was based off of that car. The G8 was Commodore based, too. Both were great cars.
