If you are thinking of using Purple Parking Business Car Parking at Heathrow Airport, please be aware that you need to read their small print. All of their advertising leads you to believe that your car will be parked in their multi-storey, secure, undercover car park where you drop it off. This is NOT true. I returned from a months trip to Africa to find that my car had in fact been driven to an open air compound some four miles away, before being returned to the undercover multi-storey car park for my return. This deal is 'smoke and mirrors'. Do not believe the claims that they make about keeping your car out of the adverse British weather conditions whilst you are away, they are simply not true. Obviously some cars are kept at the undercover multi-storey car park, but these are generally very short stay vehicles. The service offered otherwise was very good as long as you accept that your vehicle will more than likely be driven to an open air compound for storage and NOT kept in the undercover multi-storey car park where you drop it off.
