You would be a very hungry Ang Moh.
Rent here will start at 2k for a decent apartment and go up from there.
Don't even kid yourself about a car 1.5k/mo.
If you completely adapted to a local lifestyle, and were able to figure out how to legally rent an HDB flat, you might be lucky enough to save a couple hundred a month.
If you were single and flexible, it may be worth it just for the experience, but married...if I was faced with this offer, I would pass and look for something better.
I know people who's taxi bill comes to almost 1k per month...and taxis here are dirt cheap. Heck, Rob's bar tab probably is more than your entire offer!
