I was also avoiding getting this done as I felt its pretty useless for a new car. I told them to just spray the carb cleaner as they were insisting so much on every inspection but they refused and said you need to get the 'complete service' and so many other useless arguments.
TL;DR, I finally caved in at the 20K inspection out of curiosity, regret this as a waste of money now. The greed of Pak Suzuki has no bounds.
