I'd never used anything other than a taxi to get to the airport, so the prospect of parking there was alien to me.
With a 30-minute journey to Manchester Airport from my house, I always expected a bill to park there would be much heftier than a taxi so never bothered looking into it.
Throw in the horror stories of some dodgy companies taking less than good care of vehicles left with them and a taxi ride felt like a no brainer.
