Does it break down a lot and does it have good gas mileage? .. l do not know anything about cars lol so be simple:P

No! They are cheap junk, the manual trannys break easy, the head gaskets blow, the brakes are junk, the electrical system is junk, they are bad in roll over accidents. They are cheap for gas and good in the snow, but trust me they are not a good car and everything rattles on the interior and they are rough riding cars, all the interior normally falls apart by the time they are about 7 years old.
