The Old Car

So Tom's Nissan Sentra has 160,000 miles on it and is looking mighty rusty around the edges. We need to start looking for another commuter type car that is good on gas and reliable before this one dies. This car owes us nothing. We have put no work into it other than normal maintenance. Maybe we will get another Sentra. The only bells and whistles he needs are good tunes. He doesn't need anything like a Chrysler 300 accessory. Any suggestions from the blogosphere are certainly appreciated.
