Singapore's not quite the oasis you make it out to be. Have a look at how much it will cost you for a car once you get over there.
Renting or buying property is the expensive part of living in Singapore. However, it is quite inexpensive to get a live-in maid/nanny.
You don't need a car there, it's a petty way to show off. Taxis are absurdly cheap in Singapore. gothere.sg is a great site for getting places too.
