Hello municipality there has now written to me my friend, and made a nice offer for retrofitting for a DPF… Reason: “One plans in Stuttgart a driving ban for red AND GELBE badges from Jan 2010” Did I miss something there? Ok, I already noticed the advance from 2012 to 2010 for you red. But for the yellow there was so far no plan at all if when and how. Another friend had even advised me in the summer, since at all nothing too under who knows if this is being followed up even further.. Looks different in Berlin, for example, they really do this in 2010. And now this is supposed to be in fact here in S in 3 months??? (A work colleague has upgraded his VW bus in the spring to finally get yellow, the 1000s he could now just put in the exhaust..) Did I now miss an important report, or does someone just want to create a little turnover? What I have found in the media so far is however only Presse-Geraschel:Stuttgarter Zeitung Does anyone know more? Peter
