You can find a used 1998 Toyota 4runner for sale on Craigslist.com. They have tons of vehicles for sale that are cheap and used. You can also search through magazines for used cars. You sould not have a hard time finding one you like.
To repair a loose folding side view mirror on a 1998 Toyota 4Runner, slip a matchbook cover into the gap where it is loose. Any piece of cardboard will work. A person can also take the mirror off and secure the screw with plumber's tape if it is loose at the screw.
