6s!
It is a stock car from a friend, no tuning upgrade and the car has less than 6000km. He made several attempts with similar times obtained.
And this is another proof that the 231ps claimed by Mercedes are indeed more!
Sorry, but that doesn't look like 6 seconds to me, more like 7, and not very accurate using the cars speedo. My C class indicates 105km/h at a GPS 100.
