My DD is an '06 Miata, which I picked up less than a year ago. I had originally planned to just get a rental car on snowy days here, since I have connections for Enterprise here at work. But the more I thought about it, the more I decide to try to find a cheap beater. Well, I just made a deal on a 1994 Geo Prizm. Has 180k miles from the original owner. Since the Prizm is a twin to the Corolla, it's got a ton of life left in it. Got it for $400. It ain't too pretty, but it runs well. He also has maintenance records for it, so it's been pretty well cared for.
The car needs new axles up front, which I'll post a different thread on later (i.e. how hard is it for a novice to do?). But it also has some rust starting on the right dog leg. The bottom of the dog leg is eaten through. It hasn't eaten through the floor or lock pillar yet. I want to stop it before it does. I'm a complete novice at home repairs, but I want to try to tackle this myself.
I'm not looking to make it pretty again or anything like that...it's just a winter beater car. What would you suggest to halt the progress of the rust cheaply and something a novice can do?
