Still waiting for the inspection of my Lexus LS430's LPG installation. 2 weeks in the best scenario they said, I'm waiting almost 4 weeks by now. Bought that flagship in January 2009, drove a bit, discovered something was wrong with the engine, contacted the seller because he is obliged by German law to fix it, he refuses, I sue his sorry ass, we agree in court that he picks up the car, fixes it and brings it back to me, picks it up but returns it 3 months later, I have the car checked again, turns out fine (right) and now I can wait again for the new TÜV approval. 2 years and counting......................
But my 18 year old Audi 100 is completely flawless and just keeps running beautifully.
