Game top, but pure rip-off

I made it in multiplayer mode to the F40 in the top 1% (space 368), but that was not fun anymore. It was promised the "winning" an F40, fully upgraded with all the engine upgrades. I get the Ferrari - but completely blank in the base version. It took me 3x 4.38 to spend, because it would otherwise simply not have been possible to create 1% below the best.
And else is here trying the player real money invested by InApp purchases by all means.
So please be wisely here.

The game itself is good.

Edit: Reply by the manufacturer:
That was a misunderstanding and mistranslation in the game. It should not mean you get the F40 fully upgraded with 704PS, but he would have fully upgraded 704PS ... Can anyone even thinking what he wants ... For me, the system and was planned as a misunderstanding.
