Test drove a C6 yesterday and was very impressed by just how well sorted this car is! I expected the power to be there, but the rest of the car was a work of art!
Just hoping someone on here can educate me on the differences between the 05, 06 and 07 C6's.

Had been a rotary engine guy up to this point, but think I've graduated into a whole new level of performance!
Thanks,
John

 

We have an '05. The biggest difference between the '05 and '06, from what we understand, is that the automatic transmission is a 6 speed in the 06, but a 5 speed in the '05.Bob

 

Some changes from '05 to '06
*Redesigned steering wheel. The '05 had a four spoke wheel. The '06 changed to 3 spoke and is a bit smaller.
*'06 added a little chrome GM logo in front of the rear wheel wells.
*Precision Red was discontinued in the second half of '05. New color is Victory Red which is a bit lighter than the Precision Red.
*Magnetic Red Metallic was discontinued after '05. Monterey Red Metallic is now offered which is darker than the Mag Red.

Some changes from '06 to '07
*Improvements to the Bose Stereo system.
*Radio controls were added to the steering wheel.
*Daytona Sunset Orange discontinued and replaced with Atomic Orange.
*Two-tone seats are availabe.
*XM antenna now integrated into the side mirrors as opposed to sitting on top of the car.

 

I love the 2 tone interiors that the new '07 have in them. The black and gray looks really good.
