I got the modern one and I always take the items out of it before it gets too crazy. I've only ever found one rare thing in it (cardboard sofa) but other than that, it's always full of shirts and pitfalls
I TT'd to November to get my last fish for the encyclopaedia and got 5 random items in my police station. None of them were sloppy or cardboard furniture though... :c
I put mine in before I'd really thought about having a more unified look for my town and I kind of wish I could redo it, I have the modern one. Oh well, it's not the worst thing and it's placed nicely, I think. I'm pretty used to it by now so it's not like ruining my life or my town or anything. I've been sending a ton of letters to redo villagers' homes so all the stationary it has has been pretty useful.
Modern one. I chose a Classic one twice and realized how much I disliked Booker's timidness and lack of confidence. It was pretty cute at first, but it got kind of old. Right now I have a tricky pitfall seed that I don't feel like taking out because 1) that's the only place they'll appear and 2) I don't even know what I'd do with it. If I buried it to try to trap a villager or friend I'd probably fall into it.
I randomly get 100 bell coins in there a lot too. Or umbrellas, flower bags, and letter sets. It's incredibly boring to say the least. I read once of someone who got TWO Zipper T. Bunny pictures in their station at once. Plus nothing from the sloppy or cardboard set has ever shown up there. Why else would I even have it if not for trying to collect those?
What police station did you build? classic
What items are in it? clothes, stationary paper, flowers
Do you get new items regularly? yeah if i take all of them and sell it retail!
I have the modern police station since it matches my train station/mayor's office, and because the classic one looks odd for me. I rarely ever find items in my police station (and if I do, they're common items); it's usually a mix of flower bags, shirts, and/or pitfalls.
I recently built mine in Unicoira, chose the modern station because it fit the fairy tale theme better, and I like Copper quite a lot; he's so official!
I got the classic because I prefer Booker to Copper. I also have the fairy tale theme and the classic matches up better than the modern. As far as the items in the lost and found: mostly seeds, pitfalls and clothing.
The modern one. It's absolutely useless. I rarely check, and when I do, it's the same 5 freaking items. Do I have to take all of them before more start showing up or something? It's always pitfalls.
