After we posed the question yesterday, Lifehacker readers came through with plenty of handy tips for buying a car. One particularly useful notion? Take a fridge magnet along with you to check for rust and filled areas.
Reader StevoTheDevo points out that running a magnet over the body will identify areas that have been filled. And Tomas notes that it's also a good rust detector:
Apply it in the typical spots that rust would form, if the magnet doesn’t stick, then rust’s been cut and bogged.
Especially in coastal areas, that seems like a sensible precaution.
