BMW Clearwater turns odomotor readings on demo cars they sell!

I have a 2006 120i BMW which I bought from BMW Clearwater West Rand as a demo model with just a few km on the clock. I had many years of driving pleasure with this car and valued BMW Clearwater for their good services all this time. Since last year the car has been giving me trouble with breaks which is understandable due to the cars age. What was truly shocking was that I found out recently that this car's milage is ALOT more then it says through the service centre I went to (was not BMW). I was told this car has 50 000km more on then the reading. This means that BMW Clearwater sold me a car all these years ago saying it was a demo with 5000km on it, but actually it had 55000km on the clock! What a bunch of ****** you are BMW! I am buying a new car and replacing my old one, but it is not BMW just because of this. Shocked that you do this BMW, I would expect this from a low life dealership so keep your fancy coffee and waiting rooms, I will never buy BMW again.
