Mine is a 2000 M5. At that time, it was the fastest PRODUCTION car in the world.
Is the Cobra a production car...or is it a car that is turned over to Shelby, etc., and modified? The same with the C-6 Vette.
Neither of those cars comes off the assembly line as such. They are modified..albeit before they reach the buyer. They are not stock cars off the line. Are they?
The C6 Corvette is absolutely stock off the assembly-line. Specs are 0-60 in 4.2 seconds and top speed of 186 mph. (I made an error in my original post. It's 2005, not 2006). You can buy one from your local Chevy dealer. And they are very reliable for everyday use. It's a beautiful thing.
I don't know for sure about the Cobra, whether it is production or modified.
My car is Mustang Cobra, underrated at 390hp, stock. Its not even close to stock now. I buy cars to modify them and its easier to modify a car with a factory supercharger.
