car bizarre

so i bought that honda, finally, though i haven't physically picked it up & titled it etc, because i want to sell the mazda first. no sense paying insurance on two cars when i only drive 3x times a week. this afternoon i took photos of the mazda for my ad, and while i was cropping them in photoshop, i noticed something odd... my front license plate does not match my rear plate! wtf? i vaguely remember having a hard time with one of the bolts on the front, but surely i wouldn't have given up and gone driving around with one old expired plate and one new, right? nope, checked the renewal notice i just got in the mail, and neither of those plates is mine. whoever stole them was "nice" enough to replace them with other plates (likely stolen?) so i didn't even notice. weird thing is, it probably happened quite some time ago... back in november of '05, i got a letter from a gas station way on the southside (where i never go) saying i had driven off without paying for gas. i called the cops then, not wanting any trouble (VA promotes that they'll take away your license if you get busted for a drive-off), and they said not to worry about, figured it was probably a blurry security camera, or perhaps they were just off a digit and pulled my info by accident. i'm embarrassed to report that i didn't walk down the street that day & check my plates closely-- doh. thought about ignoring the whole deal, since i'm about to sell the thing (and apparently i've gotten away with it this long), but i figured i'd better at least file a police report just in case. plus, my luck with DMV is notoriously abysmal-- with my luck, i'll get pulled over tomorrow while i'm running errands & accused of stealing the plates-- since i just reported them suspicious myself. the other weird thing? the front plate is easy as pie to steal, but to get the back plate off (and replace the inside nuts, as was done), you have to get into the trunk. which means whoever it was either broke into the car without me noticing, or they had keys.
