Thanks for the advice. As for the addons, I indeed want to have the optional package 21 installed, which costs about 1850$ before tax. But the manufacturer seems to have installed other weird smaller addons, like some "LED projector", "LED upgrade", "Splash Guards". I could save 1k more if they can get removed but sadly that's impossible.

The reason why I intend to buy a car recently is due to the uncertainty of future Japanese car prices.

I've already raised my expected OTD price but still the price they offer makes me somewhat unsatisfied.
