Silvaire1, every entry point to the airfield is blocked off so you would have to fly your car in if you wanted to "park the car in the hole the airplane came out of" and you would have to pay 33 bucks landing fee and pay for the coffee if you were thirsty! Yes, GA is really friendly in the UK; you should recommend it to your friends
Robin, The car park is open, there are no barriers, it is "pay and display" only
