Just bought a brand new Hyundai Trajet, a 7-psgr MPV for just over S$1000 p.m. It is now the best selling MPV in Sing.
And re using the computer to make overseas calls, long distance rates to some countries have fallen from over $1.00 per minute to less than $0.20 per minute so I wouldn't bother with the typically inferior quality of the computer.
Contents insurance is not expensive and if you look at some of the other threads (esp the one about jewellery cover) claims are generally paid quickly.
Medical insurance is a black hole but there are advertisers on this site who can probably give you a good idea of what's available. Local policies for local companies aren't up to snuff as Tiger says .. if you are with a foreign company they may offer a more 'global' standard. Check it out. Maternity is rarely covered locally.
Sounds like your company knows what they are doing .. they probably have someone in their Singapore HR that can help you fine tune the details.
