Phone your local scrapyard, or go online, they will come and collect the car, do all the paperwork, and, at today's prices give you around £110 for the car.
You would also automatically get any tax back based on full months left, so in the case of the article it would bring the cost down to under £100!
What a load of nonsense the article is, it does however highlight the high cost of walk up tickets.
As has been stated before a more accurate comparison would be the cost of hiring a vehicle. A couple of years ago 4 of my mates were doing a gig in central London, they hired a van for 24 hours to travel from West Yorkshire, £75 for 24 hours, plus another £75 for fuel total cost £150 for all 4 of them door to door.
