I left mine for diagnostic work at the local dealers.
Went back about 4 hours later to see what they had found and when i walked in i heard they were talking about the "S55 around the back".
As i walked up to the 2 techs i asked them which one of them had thrashed it. At first they seemed stutter a little bit as to how i knew, then the older chap just blatantly apologised and said no one had seen one in the show room before so they wanted to see what it could do on a quite stretch.
I could tell they were genuinely sorry and not just saying it, but in reality i didnt mind one bit. At 500 horses, they couldnt have put the car under THAT much more stress than i do, no damage was done, it was driven by proper petrol heads and i felt quite good that they all genuinely admired the car. I also know they wouldnt have done it if it was an S320d.
I never reported this to anyone, it was between me and the techs, but now every time i go there for parts they always look after me, and i dont even ask.
Funny thing is, when i walked in and said "right, which one of you lot has thrashed it" . . . . . i was only kidding, i didnt even know the car had left the site.
Bottom line - dont go on your periods just because someone drove your car like its supposed to be driven once in a while. Fair enough you work hard for it, its your pride and joy, you'd happily sell your wife before the car blah blah blah, but so what, make someones day (or even a lifetime memory) by letting them have it for 5 minutes.
In this particular video, i dont think the mechanic did anything wrong at all. To me, it seems like the crankpot of an owner put a dash cam in the car, gave it in to the local dealers and hoped he would catch them doing something REALLY bad so he could claim. Unfortunately that did not happen so he had to have a whinge about this.
