I like it. I like it better than the 97-04 version anyway. Give The General time, I'm sure they'll release a hotter version soon enough.
That being said, the new Regal is based on the European Opel/Vauxhall Insignia that has gotten rave reviews from everyone. Including the folks at Top Gear. So no, it might not be the 21st century GN we've all been hoping for, but I'm sure it'll be one helleva nice daily driver in GS configuration anyway.
