Too much debate on an obvious advertisement article. Don't get me wrong, I have no problems with ad articles, this one for example reminds me why I did choose 1M over anything else. Because it is the real deal and it does not need to be quicker or more powerful than every other tuning masterpiece.
All M cars are tunes...by the same company who produces these cars. M is their tuning department, remember?
There is an obvious and growing effort to make competitive tunes for 135i vs. 1M and since all 1Ms are gone (in US which is the biggest market for 135i as well as 1M) it just makes perfect commercial sense. In fact, I am coming to conclusion that the kind of "annoying"
presence of 1M means a stimulant, or in other words potential big business for 135i tuners. Moreover, it means good advertisement for BMW itself for all of the following and commercial-wise much more significant M cars like the new M5 and coming M3 or future/possible M2 which will all be turbo powered cars.
1M was a test case, for a biggger purpose and I see that it did the job well.
