you have a pop-up after the last car crosses the finish line. i guess at that moment the bonus goes to your pocket.
you can check under 'finances' -> 'history' -> 'prize money'. it should be there.
Thank you, I've just realized that all my money had gone into drivers and components, which surprised me at how much I had actually spent. Speaking of money, does replacing engine and parts cost money as well?
I've gotten the sponsors with high bonuses but I don't get them. What do I do to get the sponsor bonus? I've realized that most of my money came from prize money and not sponsors.
The Sponsor bonuses appear in your finance history as "Prize Money", I don't believe that Prize money as such is awarded, to get the sponsor bonus you have to meet the objectives displayed on the home screen between qualifying and the race, alternatively you can tell if you meet the objectives once all the cars cross the line at the end of a live race when a pop-up is displayed.
