...that the upcoming Grand National will be based off the Alpha platform, making it as big as the Buick Regal and the Opel Insignia. Which makes me think, is the next Insignia OPC going to be the US Grand National GNX, complete with an LT1? Because that would be awesome. Opel has already trying to go upmarket for years, proof of that is the current Insignia OPC (Regal GS with 325 HP and 4WD). Is Opel gonna return to V8s? I can't help but dream...
