You're Under Arrest!

I liked this series, Miyuki and Natsumi were very appealing characters, but I didn't like Nakajima though. He was too much of a stereotypical bumbling fool when it came to him and Miyuki. (Not that she handled it any better). But other than that, it's a good series.

And I want to add that in addition to the 4 episode OVA, the 48 episode first season and the movie and specials, there is also a 26 episode second season. That season has not been licensed by any foregin company yet, so the only way to see it is by getting Japanese DVDs or if not that, the "other" way.

I recommend this, it also has good rewatch value. (for me anyway)
