Can you buy a car with a credit score of 560?

No , you need to build up your credit rating. 560 falls your credit ratings in a poor category.

You should make sure that you take care of the following things;

Electoral Roll

No missed payments

No outstanding high debts

No country court judgments

Not more than 3 + credit application in 6 months

Also keeping your credit in a smart way. Not using it too much.

After that you can register yourself with credit expert ie experian and they can check your

score time to time as you have 560 at present. keep it tracked and see what alerts you are having while building up your credit strong.

After that when your score becomes fair atleast then you can take a chance.

but at present i surely recommend NOT to apply for it.
