You can either sell them for a relatively small amount of money or you can scrap them. Or, if you really like your rusty car, you can spend a bit of money on 'doing it up'. By this I mean giving it a paint job and taking real good care of it and fixing everything that needs fixing. It also depends on what car it is. If it is vinatge, 'do it up'. If it isn't, sell or scrap.
You usually will want to get an estimate in order to determine if your car is worth fixing. Many times, if it is your engine, it is not going to be worth fixing.
because of weathering
Rusty cars are usually a bit weaker then ones without rust. It chips of easily and so that is why a rusty car is dangerous. Especially if the main body or chassis is rusty. Weakness on the chassis mainly could be a definite killer to a car. That would mean changing the chassis. I would just get a new car by then.
Yes it can
Jacob is fixing the 'Rabbit' which he saved from the scrap yard and he is fixing it for himself so he can drive it around
my car is being fixed by the mechanic
its harmful because when metal goes rusty it looses it power and then eventually the car will fall apart.
