Costs for service at MB branch

I’m already ready to pay salted prices for good performance. But lastly, the invoice at my branch for the service seemed quite high: Assyst B: 680,00 € Renewing brake fluid: 140,00 € Change of transmission oil and filter: 870,00 € TÜV + AU: 175,00 € Change of tyre + storage: 160,00 € Total: 2.025,00 EUR The change of transmission oil, tyre storage and brake fluid change cost a whopping 20% more than 4 years ago. i MB 77,- EUR, on the other hand at Amazon the one from Bosch 27,- EUR. Does that seem to me to be somewhat extreme?
