I once had a seven series - and I could drive 105 all day long, and it was like 55. I even once drove 105 miles in 60 minutes.

Edit: Funny story. I was driving from Boise to Portland and was between Ontario and Baker City. My wife was reading a magazine and we had on soft music, and I snuck it up to 100 and drove there for about 10 minutes and my wife didn't notice a thing. My wife comes out of her ether and looks at the scenery, and then looks at the speedo, and says, I know you love this, but you'd better slow it down.
