The F1 Ferrari team received a MINI Cooper S from BMW/Williams. The car was offered to them earlier this weekend at Monza by Mario Theissen on behalf of BMW. With the MINI, BMW congratulates the Ferrari team with winning the F1 championship.

…”When in about 100 years BMW is winning the championship we will offer them a red Fiat Panda,” Luca di Montezemolo (Ferrari president) joked in return.

Sounds like a pretty poor trade to me! You can see photos (including a Ferrari logo on the roof!) and read more here.
