Hello! Our car wouldn't start this morning, and our neighbor tried to help us jump it with no success. It has a decent amount of corrosion that needs to be cleaned off, and we may just need a new battery. But does anyone know more about this who may be able to take a look before we get it towed to a shop just to be told something very basic?? (Or, alternately, that it's not the battery?) Or, I guess, can anyone recommend a reliable car place that doesn't charge like crazy for the diagnostic part? Thanks!
