I heard that it is illegal to sell F1 tickets...
It is legal to sell F1 tickets as long as they're not sold for a profit.
here's a quote:
Singapore GP told The New Paper that it is aware that some ticket holders are reselling their passes. The same thing happened last year, when some people marked up the resale price.
Its spokesman said: 'We do allow reselling at face value. But if a reseller marks up the price, that's speculative and it deprives real fans from watching the race.
'We recognise that people have legitimate reasons to resell their tickets. If you sell below the face value, that's not a problem, because it doesn't deprive anyone of the chance to watch the race.'
