9. Saturn ION Redline
GM was experimenting with a few affordable sports cars during the early part of the decade. Saturn was the guinea pig brand for experimental models. The redline brand was attached to the ION and the Vue as a performance-oriented option. Then there was the Greenline, which was the hybrid-oriented product line. When you look at the options, the ION Redline looked the part of a performance car. The ground effects kit was aggressive and the spoiler gave the car a mean look. But performance-wise, the car didn’t deliver for the price. Reliability on the ION was spotty.

Sales never really approached the numbers that GM had hoped. The ION Redline should be at the bottom of your list when you are looking for a sports car. Nothing about the car has held up well over the lapse of time. Saturn ended up being disbanded after the 2008 recession, and the Redline brand vanished as well.
