I also strongly question the £15 per day figure, I'd like to see the assumptions placed to get there.
2005 RAC cost of ownership puts the cost of running a Vauxhall Corsa 1.2l at £9.36/day. and a 1.6l Ford Focus at £13.04/day. Since fuel prices have increased some 40% since 2005, that puts it up to some £10.61 for the Corsa and £14.11 for the Focus.
Once you add in other factors (inflation, extra cost of driving in London (higher insurance, paying for a parking space, congestion charge, higher fuel costs than national average)), £15 a day sounds like a reasonable figure for a family size car.
