In the days of old...
Fall out of a nightclub at 2ish, get picked up by a mate that had a V12 Jag, from Leicester down to the Smoke in around an hour and 20mins, straight off the M1 on to the Edgeware Rd, and park up at Embankment, and have bacon rolls and coffee from an all night stand, and watch the sunrise over the Thames and Tower bridge, then head home at about 6ish

One tank of fuel to get down there, and the other to get back!
Just Awesome
