I hate to disappoint everyone but what you are all looking at is simply a European homologation version of the STS-V which GM begins selling in Europe next spring. The tail lenses are identical to those found on the regular STS sold here in Europe. The reflectors under the bumper, likewise, are simply a European requirement. The US is the only country in the world that goes its own way in matters of lighting. The rest of the world including China, Japan and all of Europe follow the European approach to lighting which means principally that turn signals need to be amber (yellow). In the US, there is no rule but then again in the US there is no respect for lane changing.
We will all recognise the upgrades to the 08 STS beause there will be changes made to the front grille and rear light clusters. Furthermore there will be a (needed) upgrade to the interior. The original 05 interior was good but not great - hopefully Bob Lutz has finally been able to stamp his desire for Audi-quality interiors on the STS. My big question to all of you out there is whether we will be seeing an 08 STS V?
