I bought my 2005 Cobalt 2 door in March 2011. It had 54,000 miles on it, and it ran like a brand new car. It has all the options, except a sunroof. My son drove it for his summer job, and the engine did fail, but it was fixed through the extended service contract I purchased. Only paid the $100 deductable, and a new engine was installed. Now it runs even better than before! It still looks like a new car, not one spot of rust at 8 years old. I'm now driving the car, and I have a 2010 model, cause I really like this style of car. They both run beautiful, and I have all the maintainence done as the manufacturer recommends.
I like the sporty look of the 2 door coup, I have the rear spoiler, and it makes the car look so cool.
The interior did have some paint chipping on the plastic parts, but my son took care of that, by painting them, and now it looks awesome!
