Is it me, or does the lack of license plates (front and back) and any registration or inspection stickers on a vehicle a cause for concern?

There has been a white Range Rover (late model, fairly spankin’ new) parked in our visitors parking area for the last 1.5 weeks. It comes in very late at night (probably past 11 or 12 at night because I generally don’t see it earlier than that time) and leaves fairly early in the mornings (by 7:30 or so). I know because it’s not there any time I’ve looked out the window at nights, but is there early in the mornings when I wake up.

The vehicle has no front license plate and has no registration or inspection stickers on the windshield. Even brand new cars (with a temporary paper license stuck to the rear windshield) has the dealer inspection sticker on the front windshield.

In the “heightened” nature of our post-9/11 era, I would have thought that my local P.D. would be interested in such a vehicle. But when I called, they seemed to be more interested in a “ticketable offsense,” meaning if there is no violation to be ticketed, they will not come out to look at it and/or investigate. In the officer’s words: “since it’s on private property [the condo parking lot], there must be someone who will want to sign a ticket against [the vehicle], and then we’ll come out to take a look at it.”

Are you kidding me? Doesn’t this vehicle remotely sound suspicious?!?!?! Even just a little?

Am I being paranoid?
