Aw come on. That 333 UKP difference buys you a lot of bragging rights on PPRuNe!
Me, I live about 15 minutes by pushbike from Amsterdam Schiphol International airport. I'm still working up the courage to drive 45 minutes to Rotterdam, where my flying club is based, fly 15 minutes back to Schiphol, have lunch there, fly back to Rotterdam and drive back home. Just to be able to say I did it. Never mind the 350 euros or so that this little adventure will cost, in total.
General Aviation is normally not about the most economical mode of transport. It's to a large extent about having disposable income and doing something with it that we love. If flying straight into Gatwick fits your desire and budget, go for it!
