With just a few days to go before this year's SingTel Singapore Grand Prix gets under way, a limited number of tickets are still available for the sixth edition of Formula One's only full night race.
Since sales began in February, 11 of 20 categories have been sold out.
Fans can still purchase three-day passes for the Pit, Padang, Turn 2, Stamford and Connaught Grandstands.
"We have already exceeded last year's total attendance of 84,317. But as we are a build-to-order circuit, we are adding additional inventory where we can to meet the strong demand," a spokesman for race organiser Singapore GP said.
"However, this inventory is extremely limited, so fans should secure their tickets now."
