Which of these two cars are better:?

The Camry is probably better, overall. But, if you're considering buying a used car from a person, spend $100 or so to get it thoroughly inspected by a mechanic. Even if the Camry is a better car, new, than the Malibu, but the previous owner didn't care for it properly, it could have some serious problems. Trust me, it'll be the best $100 you ever spent.
