Inquiry

I was watching the news the other evening and saw that you could get a free credit report. So I called my local credit bureau and was told that if I got it from them that it would cost $15. But that I could get it online for free, so I did so. My printer is not working so I could not make a copy but I did notice an inquiry from an automobile dealership that I have never been in. That really bothered me. How could they pull my credit?? So then I went to the local credit bureau to get a copy and that inquiry did not show up. How could that be? The inquiry was dated 7/17/07.
Could you please help me with this? Just let me know what information you need.
PS
My credit rading is very good (over 800) and I would hate to have an idendity theft ruin what I have worked so hard to obtain.
-----------------
Different bureaus were pulled up
The inquiry in on one burea and not another
There are 3 credit bureaus
that any potential creditors might use and some use all 3
800?
Forget about an inquiry.
800? Gosh. You see those once in a blue moon at a car dealership.
YOU ARE NEON CREDIT PERSON. take a chill pill
