Top Gear on BBC. My father got me into it, and the guys on the show are just wacky. Am a bit of a car nut here as well, so I just love it.
When I was a teen we used to watch Are You Being Served?, Keeping up Appearances , and Vicar of Dibbley on PBS. 
Wow, I wish I had a silverware set from 1715 lol
I'm a die-hard Rowan Atkinson fan; my favorite "imports" are:I am such a fan of the Vicar of Dibley. It's one of my top 3 favorite shows, (Golden Girls, Vicar of Dibley and Masterpiece Theatre.)
There was also a show on a loooong time ago called "Man About the House." It was the British show that Three's Company was based on. I liked that one quite a bit.
ETA: I just thought of a great kids show that I watched when I was young called "The Tomorrow People." That was done by the BBC. Loved it!
My daughter really likes "Dancing on Ice," which I believe is the British version of "Dancing with the Stars" (except it is figure-skating!).
I never thought about Netflix - do you think they'd have it?
My all time favourite US show is not much of a surprise - Friends. We watch it through time after time and I STILL cry when Rachel says "I got off the plane"![]()

I've kind of gotten hooked on a Korean series (with English subtitles) called "Dong Yi" that's airing right now. It's sort of a Cinderella type story that's set in the late 1600s (I think). It's a bit slow but interesting and the costumes are gorgeous!
Oh, after typing I realized you probably mean on of the British shows...always loved Dr. Who!
90% of the shows we watch are British Shows:
Doctor Who
Torchwood
The IT Crowd
The Mighty Boosh
FM
Skins
Jonathan Ross
Graham Norton
Gavin and Stacey
Nevermind the Buzzcocks
Friday/Sunday Night Project
Little Britain
Catherine Tate Show
etc....
in general the shows are just better over there than over here...
