Even the more positive stories in this thread are pretty horrifying. Really sorry for you... I simply now hardly drive my M3W - the fear of imminent failure or expensive hassle is overtaking the few moments of joy. And the cost per mile is getting close to Lamborghini territory!!

I worry for my Oct 2012 chassis, and many other issues but my car has been fairly reliable compared with many!

Hopefully solutions and sense will start to prevail but it doesn't seem so. I fear for what the future will hold! Now - cheer up! Stock markets have just collapsed faster than M3W values so perhaps the money is better spent than we all thought!!!
