We got a Saturn Redline about a yr. ago. It's basically the same as a Cobalt. It has been a GREAT car so far. We were a little dissapointed with it's stock performance(15.0-15.3 in the 1/4). I changed the pulley to a 3"(stock is 3.25) and ran a best of 14.6@96. It has held up great so far, and I'm rough on it when I drive it.
The SRT4's are definitely faster,and have a much better aftermarket, but it's picking up for the RL/SS, and there aren't 10,543,000 of them around here.
