I always thought the GT was designed after the Corvette. It turned out it was the opposite. The Corvette was designed after the Opel. There was not a lot of room in that engine compartment for much more engine. Heck, one thing I loved about the car is that even though I’m over six foot, I still fit in it, but just barely. I was amazed, after I had owned the car for a couple of years, that the drive train tunnel is not in the center of the car. The passenger side is rather tight. :-)
I’m amazed that GM is closing the Opel plant in Germany in favor of connecting with Peugeot.
