I notice lots of people are having trouble with their cars. If you need low-cost repairs, try contacting a local mechanics school or high school with an auto program. I also found this site that offers emergency aid for auto repairs:

Want a free car? If you don't mind driving a car that is covered with an ad, or letting a company cover your car with an ad, you can check out these sites and apply for a car or a cash allowance. The sites claim to be free. I'm not affialited with these sites and I can't vouch for them.
