I'm looking for a long documentary about Princess Diana's death which came out around 2007 or so. It was done by a British reporter and it was several hours long divided into about 10-15 parts. He bought the same Mercedes as the one in which she died and investigated everything from the brakes, to the airbags and also the events following her death like the ambulance taking forever to get her to the hospital. He also looked into the past history of the British royal family. It was very compelling but unfortunately I have not been able to find it since, I don't remember the name of the reporter or the name of the documentary. I just know it was several hours long and divided in many parts. I believe I saw it on Dailymotion back in the day. I would appreciate if anyone could point out to me what the documentary was and who produced it.
