As you know I won't be at Sebring this year but I wonder if any of you who are going require the free services of Gatwick Parking Ltd (Handcross Branch)? You'll have to park next to the Commer but if you co-ordinate a cab or two it could show a big saving on the long term rip-off merchants at the airport.
Send me a PM if I can help.
What about for 5 weeks in July / August ?
