My sister and her husband bought a Saturn Ion in 2005...
In the past 100,000 miles it has gone through a bad catalytic converter, 3 ignition switches due to faulty engineering in the factory security system (when it gets cold outside the switch goes bad and the car won't "recognize" the key), bad swingarm bushings at 40k miles and a worn out clutch at 70k miles.
My brother in law says GM can suck it. They're buying Japanese next time.
