I'm helping a car-challenged friend buy a used car. It's come down to a choice between a 2004 Hyundai Elantra or a 2004 PT Cruiser. Both are one owner, low mileage cars in excellent looking condition. Both have 5-speeds. I'm just wondering if anybody knows of any engine-related issues with either of these cars? I know the Cruisers have lousy gas mileage for that kind of car. But as far as engine longevity and reliability, does anyone know if either one of these have any skeletons in the closet? Excessive oil usage? I don't need suggestions to look at something else or any fanboy bashing. Just any pertinent constructive criticism of these two cars or their engines. Thanks.
