Living in the intense spotlight at the top of the tennis world can force young athletes to grow up quickly - something Andy Murray has found as he has powered up the rankings this year.
The top-ranked British player - who reached number two in the world earlier in 2009 - only passed his driving test in July, but has already shelled out on a Ferrari 430 supercar.
However, the reported £100,000 he paid for the dream machine could be doubled by the cost of insurance for such a young and inexperienced male driver, at the helm of a car which can do nigh-on 200mph.
According to the AA, which asked a panel of 20 insurers for a quote, 'most wouldn't touch it' - though the few that said they would take on the risk would be likely to ask for around £100,000 a year.
While it might be premature to suggest that the twenty-two-year-old - who split up with his long-term girlfriend last month - is having an early mid-life crisis, it's been suggested that buying the boy's toy has helped him get back into the singles' market.
And although the pictures of Murray pootling around British streets have just emerged, they could be a few weeks old by now. He has been in Miami for the last two weeks, keeping his followers up to date with his punishing training schedule via Twitter, the micro-blogging platform.
