I'm not trying to be flip. You should try to look up your own data sometime. In many states, with just your plate number, I can request your info. The DMV will give it to me unless you've requested and presented a reason for them not to. Some will notify you and possibly give you a few days advance notice but with action on your part I will get your information. The cost here is less than $100 typically.

Or a PI. The cost there is less than $2000 typically.
