question here.

my friend calls me today and asks me if i can help her out by co-signing with her so she can lease a car. i guess she said it would be better for her if she had someone to co-sign becuase she is already paying off one car loan, cuz after she leases this car she will have 2 cars.

in your opinion, would this be a good idea for me to help her with or would you not do it? how would it, if at all, affect my credit?
