Yesterday Rick Conti reported that the aluminum shifter knob on the 2008 Manual Transmission-ed Corvette has a different pattern.
In fact, the same is true of Automatic Transmission-ed Corvettes. The 2007 aluminum has a pattern. The 2008 has smooth unpatterned aluminum. I think the look overall is better for 2008.
This is one of the many changes we reported back on April 30 in the blog "Corvette Museum Announces 2008 Corvette".
