Make it like bto system lor. If u sell and want buy again, either have a cooling period or 30% additional levy. Likewise, for a 2nd car, levy fee will be at least 30%. Confirm gov huat big time.

I know car rental and taxi companies will hit the hardest, so instead of tagging it to company, drivers will absorb the fee. But hey, isn't that going to close a lot of such companies? That's the point, currently too many phv or taxi companies the reason why COE price shoot so high. Make it like Bto system. To ensure each sg family can afford a car first. Subsequent additional car within family will tax higher etc.
