I don't know about the prices in Japan but these prices before taxes are also feels ridiculous to me. A wigo for 6.9 Mil? Since we're comparing with before crisis (5 years apart), these prices maybe correct. My Vitz cost 3.7 mi with taxes back in 2018.
Ok the prices aside, what about the taxes? They only talk about 18% VAT. And if someone thinks that's it, they're gonna be surprised. Excise duty which was based on engine capacity (which also caused more under powered <1000cc cars to flood here), PAL, NBT, Luxury Tax will be included in my opinion unless there's a complete overhaul in tax structure.
