90,000 inspection SL500 R129 Bj97

Hello, I once had a Mercedes offer for the 90,000n inspection for my SL500 and I had to be amazed, it is my first Mercedes vll. therefore the question to you if all this is so normal… 00-3016 Maintenance service 90,000 52 AW 527,80 42-1423 Brake fluid change 4 AW 45,80 15-1010 Spark plugs and mount 17 AW 209,95 07-5563 Fuel filter renews 7 AW 80,15 40-1450 Wheels all from and mount 7 AW 80,15 MN916002 012100 Clamp 2 Pcs 3.02 M A002 477 26 01 Fuel filter 1 pc 20.61 MA003 1596703/26 Spark plug 8 pc 30.40 MA119 180 00 09 TS Filter Insert 1 pc 14,47 MQ0245901 Engine oil MB 229.5 8 l 155.20 MA000 989 08 07/13 Brake fluid 1 17,11 MA999 999 99 Disposal Brake fl.1 2,20 Final price net 1186.86 Final price gross 1412.36 I already thought the Mercedes driving is a bit more expensive, but if I look at the individual positions then I have to ask what they are doing or if it is really so complicated i I don’t know how to count the AW, but someone can also say something. For mounting the tyres almost 100 euros? And what do they have to do at all? I don’t know brake fluid change with mounted tyres is that possible with Mercedes? 250 euros to turn 8 spark plugs off and on again? Are they so difficult to access? And what do they do for the more than 600 euros at the service? Unfortunately, I don’t have the German maintenance booklet yet because it’s a Japan reimport han Delt. Everything that goes towards, 8 enders and then gets upset about something like that I don’t need here… about all the other answers that help in the context I’m happy!
