You can import your own car, but it must be less than 2 or 3 years old - can't remember exactly, but when we looked into doing it there were lots of restrictions, eg you have to take the car out of the country with you when you leave. Decided it wasn't worth the effort as second hand cars can be bought locally at decent prices. Expats leave quite regularly as contracts end, so there are often cars and household goods for sale.
There are SIN-style food courts, but also a couple of hundred or more small local restaurants where you can eat really well for a few dollars. You can see why I chose this user-name
