those are parts that came with shitty paint from the factory, and it's in a salt environment. of course there's surface rust on them.
there is ZERO rust-through on the vehicle, with ZERO unibody/floor rust. hell, what rust there is on the axles doesn't even count...if I can turn a bolt, it's not rusty.
this is almost the exact same deal i got on mine. same options, 5 speed etc. got it with 160,000 miles on it for 300 bucks with very similar damage. its been the most reliable vehicle i've ever owned. buy it, fix it, wheel it. just my .02.
