Credit Card Lounge

I have real bad credit I believe, because I even have a foreclosure in my credit report.I am now trying to find some kind of credit card offer that will let me borrow like $500.00, but I do not want it to have a terrible high interest rate nor a Deposit fee nor any other fee. I am trying to rebuild my credit because I only think that I will spend like $50.00 a month and try to pay it back in full the next month. I have tried to look into the many “Bad Credit” offers online, but I need some guidance as to what to do because I do not want to be cheated like many CC do as I have found out. What do you advice?

I have bad credit, but I managed to purchase a new car with a high interest rate. My auto loan is through Capital One. The credit card offer is from Capital One because I’ve made timely payment to them on the loan for 1 year. Would accepting the card help raise my FICO score or hinder it? I thought that applying for new credit cards lower the score.
