World champion Jenson Button had to file legal action to get Mercedes Grand Prix to hand over his title-winning Brawn GP car.
Button had it written into his contract that he would get to keep one of the cars he raced if he won the world championship.
However, the rebranded Mercedes Grand Prix team, which bought Brawn GP over the winter, initially refused to hand over a car.
Consequently, Button's company, JB Next BV, filed legal action in London's High Court in April against the team.
The team's court filings reveal that it couldn't give Button a chassis as, "We have no spare 2009 chassis as limited quantities were manufactured for the 2009 season for cost reasons."
Instead, it offered to build Button a replica - something he rejected as he said it wouldn't be as "unique and special" as one of the cars he actually raced in his title-winning year.
However, the case did not end up going before a judge, as Mercedes agreed to hand over a car.
