Rust depends on what area you're in. I've only seen one in Colorado with rust (without having prior damage), from members on the coasts I've seen plenty... usually in the wheel wells and under the spare tire.
Blown head gaskets are VERY common and as they're 20+ years old LOTS of general wear and tear is common: suspension, bushings, seals, hoses and vacuum lines, valve stem seals, fuel filter and often pump... Those are what I'd say are the most common issues... oh, and turbo oil seals.
