I know that in option 2 you pay and exchange your existing cab for the new one, while for the first option, you simply pay a flat rate. What I'm asking is why does option 2 look so much more expensive than option 1? Consider a flat rate of ¥998,000 compared to ¥570,000(¥10,000+¥560,000) AND a Taiko cab. Going solely by value alone, option 2 is so much more costly than option 1, which is why I'm confused, since option 2 is supposed to be a better bargain than option 1.
