I worked in a Large Ford dealership and we were on 1link.Some of the problems included long waits for authorization(computerized),"we dont pay labour for that op",you only get paid what 1link say is the going rate for your area(approx 25% less than retail),A**holes turning up at 5.30pm with broken down Mondeo Tdci`s demanding courtesy cars(which are all booked out the following day).I`m sure they will also require discounted manufacturers parts to be used on cars still under warranty(not sure how that would work for independants).
