This site does give you an in depth credit report AND your score (it might ask for an additional charge to disclose your credit score - but the price is negligible - but that's if I'm remembering correctly).
On a side note: don't get all three of your scores at once and I'll tell you why: it's a good ideal to monitor your credit throughout the year and if you get reports from all of the credit unions at once, you'll have to pay to check again that year. I've worked it out to where I check my credit report and score every 4 months. Call me paranoid but I do like to know what's going on with my credit especially considering it's important for things in the future like getting house loans and it's also beneficial in weeding out potential identity thieves (which I hope isn't the case with your mom).
Just my 0.02 cents on the matter though. I hope your mom gets the car loan thing all sorted out!
