I still have my '94 Sentra I bought in high school. But right now it's sitting dead in the parking lot of my apartment complex because I let the battery run down. Eventually I'll get around to replacing it (there's an auto parts store less than 1/4 mile from my apartment, so it'll be no big deal to get a new battery and swap it out) and I'm going to install one of those shut off knobs to keep the battery from draining down in the 3-4 months between drives.

The problem now is that the weather is so beautiful that there's always somewhere I'd rather being going on my bicycle than mucking around with my car...
