'98 Saturn SL2. I have about 90,000 miles. I get an average of 25 miles per gallon (a bit less city, a bit more highway). It cost me $20 the last time I filled it up, and a tank lasts me about a week.
No reason why I won't have it for at least another 2 years. By that time my parents will be ready for the Cadilac they've been wanting, and I'll buy there Crystler Concord from them.
So sorry, Detroit, no new car purchase on the horizon from me!
