It would take you a half hour to become comfortable with a stick, but there really isn't much reason to buy one; in most cars of reasonably late model, the automatic is essentially as fuel-efficient as a stick, and automatics are better on ice. I couldn't agree too strongly with the others about the Japanese car; a Toyota Corolla would be a good place to start. In your price range, and with your plans, take a good long look at the tires, and if they're bad, make the dealer an offer that includes newer tires. They can usually switch tires between cars at no cost to themselves. I-35 can be a wicked highway in the winter...I have driven all over North America and much of the Middle East, and the absolutely worst conditions I ever encountered anywhere, any time, were on I-35 between the Minnesota border and Des Moines about 5 years ago, after a February ice storm. You need good tires...If you're short on cash, you also need high mileage, the way things are going, and a Corolla will get 35 mpg in a mix of city/highway driving. A small Honda will do the same...I'd be really nervous about a Cavalier, especially as a used car. They're often a first car for kids, and do you really want to own a car that might have been a first car for a kid? Get in the car, turn on the radio and check the presets. if you get five out five metal stations, look for a diffferent car.
