I'm taking the liberty of spending €1,000,000 to avoid converting prices back and forth but the Finnish prices I'll use more than compensate for that. I'm limiting myself to cars that currently have a list price in this country.
Audi S8
€165,500 + €42,300 optional extras = €207,800
Ferrari 599GTB F1
€338,400
Mercedes SL55 AMG
€215,500 + €55,000 optional extras (including performance package) = €270,500
Mercedes GL 420 CDI
€127,000 + €34,680 optional extras = €161,680
€207,800 + €338,400 + €270,500 + €161,680 = €978,380
