Hello, I did my Bella for the 40.000er service and must of course do all this officially so that my mobility guarantee is preserved!!! 660€ this is the absolute hammer only working time 400€ rest material! Supposedly for this service a working time of 4.5 hours is calculated and at 90€ the hour is the same! ! ! What do you say? Am from Austria how are the prices in the federal states and in Germany? I am already curious about the price differences! Greetz
