If you buy a pair of jeans at the GAP that don’t fit, you simply take them back for a refund or swap them for a better-fitting pair. But what happens if you buy a new car that doesn’t “fit?” It’s in the shop almost from day one with problems the dealer can’t seem to repair. Uh-oh, you might just have a lemon. And unfortunately, taking it back for a refund or a new car is much more complicated than replacing those straight-leg jeans. You should know your rights so you don’t get squeezed by a lemon.
