We've used this valet parking company 6-7 times ,and always spot on , £35-45 ,depends on times obviously, just go to their premises, (after booking !) they take you to the terminal , coming home , clear customs ,give them a call ,pick you up , on your way. If I can do it ,its easy .

Manchester Airport Valet Parking
We only live 20 miles away and this is better than parking costs . ( hope this makes sense , had a couple of beers !)
