Run away. Avoid them like plagues. These cars will ruin your life.
If you want to buy a good first car, spend the extra cash and get a Suzuki Swift, you won't be disappointed. I know it costs more money, and fuel economy is not that great, but it will not drain your bank account. Just make sure to find one in good condition.
I could recommend buying a Cultus (new one) and Picanto, but I have no experience with them.
