Unveiled alongside the 40th Anniversary GTS, the HSV Senator Signature SV08 is a limited edition of the more luxury-oriented version of the Holden Commodore. It's a bit more exclusive, with just 20 equipped with a manual transmission and 30 automatics. It's also a bit more expensive, with a price tag equivalent to just over $57,000 in Ameros. For that, you get additional chrome accenting on the side mirrors and door handles, and 20" rims standard. More importantly, you still get the same 412 HP 6.0-liter LS2 V8 as the normal HSV Senator. Too bad we can't get something like this in America badged as a Buick Park Avenue.
