Actually I bought it just to be able to get my 2 trophies for speed. Spa 24, Sardena, de la Sarthe are actually very nice ways to have super fun and make not bad Cr. per hour, but it's just me, IMHO.
I don't care anymore, I have about 410 cars in my garage, I need few more and I've never driven super boring car on Tokio Experss East Clockwise.
550.000 Cr. per hour, far less than 3.300.000Cr. but you can do it AFK, so you are not bored to death at the end .
Best he can get when his menu is not complete.
