The Bridge or "Bron/Broen" is a Danish/Swedish joint-production where both countries' police forces must join together to solve the murder of a woman halfway across the border of each country.
Saga Noren, real name Sofia Helin, is the lead character and a brilliantly thorough detective with comically poor people skills and social graces. You come to realise she has Asberger's Syndrome which goes a long way to explaining her character! But the real star of the show is her classic 911, which Saga Noren drives in every episode, fast! Susannah and I have just finished season 1 and we're champing at the bit for season 2! If you've seen The Killing (AKA Forbrydelsen) you'll like The Bridge.
I've clicked on a couple of forums and the guess is it's a 76/77 Porsche 911. I love the look without a big wing on the back. Watch the trailer for the show here:
