I had it and now after 3 years I have to pay for servicing.

  How bloody rude!
Corporate, in 2007, was 3 years servicing costs (ex things like brake pads, etc) and a set of mats.
I never paid for the loan car at service time but I don't know if this was part of the plan or just good service.
At the time I worked for a multinational so all I had to produce was a statement on letter head re the number of company cars they had.  Didn't have to be LR.  I think the minimum was 50 cars but I could be confused with VW who had a similar rule.
