90000 Inspection i30 CW

Good evening, I drive a Hyundai i30 CW built in 2021 ,159ps, automatic 88000 km. It’s the 90000 inspection and probably also the spark plugs. My dealers want to have over 800 € for this inspection. I find this damn expensive and wanted to ask if someone already had the inspection and what you paid for. Thank you very much Greeting from Duisburg
