2007 Saturn Ion Red Line Reviews
I bought this car with 26k miles on it. Having no idea what the previous driver treated the car, I am at almost 42k now and having to replace the serpentine belt. Also, the paint on the hood/front bumper chips and dings way too easily. Other than that, the car has great performance, excellent stopping power. When it's freshly washed/waxed, it does turn heads. People don't usually expect the kind of performance this car has, from a Saturn. Awesome car, I absolutely love it. And it's easy to work on yourself as well.
