Hallo!
I can't find any info about windtunnel. What it's aim?
Also advertising. Does it really effects the sales? :blink:
Thank you.

The airtunnel is used for your sports cars and will help develope faster cars.

Depending on how earlier or late in the game you will have to use quite a big amount on advertising but yes it has effect on your sales. But not as much as developing a good car has, and the price of the car.

Thank you! Also, is it possible to speed up race events. 14 laps are too long :wacko: )

no. You can't speed it up as fare as i remember my own game :).
