Mongoose Motorsports produces an unauthorized replica of the legendary 1963 Corvette Grand Sport. GM doesn't like that. They're suing the Ohio-based company for trademark and IP infringement claiming irreparable damage done to the Corvette brand and their bottom line.

This brand-new Corvette Grand Sport, spotted by a Corvette Forum member outside a dealership in his local town, has something wrong with it. Can you spot what's wrong?

The 2010 Corvette Grand Sport accelerates a touch faster than a normal 'Vette, handles and stops a little better than a regular Corvette, but GM's thinking 50% of sales will be the GS. Why? It's all about the parts list.

As 1.5 millionth Corvette comes off the assembly line, GM's announcing pricing on the sub-Z06, sorta-like-a-Z51 2010 Corvette Grand Sport coupe will start at $55,720 and the convertible will start at $59,530. New pictures of both below.

Absent since the C4's demise, the Corvette Grand Sport is back for 2010, this time sporting wider Z06 bodywork, larger brakes and the option of either a Coupe or Convertible. Another commemorative sticker package? Not-so-much.
