The best one I have is with a Mondeo work car.
We had a slight miss hap involving some road cones, a lorry and a sleeping driver!
To cut it short our Mondeo was side swipped and ended up with both doors, wings damage.
We had it recovered to a local Ford dealer.
After 3 weeks wait i got a phone call to say they where about to look at it.
another 2 weeks later they phoned me to say that they were not sure on what the damage was, so i ended up going down there, it's not hard to miss the damage!
When i get to the garage i find them looking at a Focus not our Mondeo....
So after a lot (lots and lots) of argument and shouting i find out that the whole time they where actually looking at the wrong car!!
Our Mondeo was stolen out of their yard and torched around the corner and they had not noticed!!!
Our lawyers sent them court action and they sent back a out of court settlement, 3 brand new fully specked Mondeo's and a Focus for me!! :D :D B)
A very bad start but a good finish!!
