I always thought heathrow airport car parking was extortion but Oxford street in London has taken the title as the worst.
If you went today the GT-R in the reserved space on the left of the entrance was mine thats where I park. Big spaces and safe. Middle of London for £1.60 an hour parking, Most of the time I get in before 7pm and I'm out after 6pm so now paying congestion zone charges either when I park in there or Grosvenor Square.
Welcome to London... Lol to be fair there's a lot of single yellow around there that you can use after 6.30 for free
