Toyota corolla: a solid little car under the rust.
2004 Toyota Corolla CE
The car needed some maintenance when I got it (it was rusty, having sat for several years). There is superficial rust on the undercarriage, which affected the suspension, heat shields, exhaust system, and brakes/brake guards. Some of the rust was hazardous, leading to a flat tire, a loose heat shield, and needing to replace parts of the exhaust system. Now that these issues are (mostly) resolved, it is a pretty reliable little car. It is kind of dinky to look at, but it gets pretty good gas mileage, it is comfortable, and it takes me a long distance.
