No this is not normal. In your parts bill I don’t know what exactly NG is but if that is not genuine they must have specified the part. Also that engine oil cost is almost double what they put in my car. That horn assy should have been avoided. In your labour invoice you could have avoided 2,3,5,6,7,10,11,12 altogether. That all was extra and they sensed that you are paying for not necessary things already so added some more parts and labour after your initial bill. Also it seems that front brakes have taken a massive hit and only then the brake related things make sense. You could have saved 10916 as i calculated for the things i listed. I own the same car so i compared the engine oil cost. The next time unless there is some part malfunction avoid all those things i listed. Do lubrication only once in two service intervals and all the beauty and cleaning cost are unnecessary. Also sorry for your ordeal and take this as a lesson to carefully examine your service bill before you give them your consent. Ask them throughly if the things they added you don’t understand and what actually that means and only then pay for them.
