Zia,
The whole singapore market is relatively new compared to jap exports, however my company has been exporting cars out of singapore for 5 years and we ship approx 120 plus cars per month to The West Indies, Cyprus, New Zealand and various African Markets.
You are certainly right about new cars being very expensive in Singapore, but what most people dont know is that the price of the car brand new is made up of approx 90% taxes. Now when you export the car out you get a refund from the govt on the taxes making the actual price of the car very cheap.
To give you an example of one of the cars that we sold to an Agent in Pakistan, it was a 1999 Mitsubishi Galant 1.8A GDI in silver with black leather interior and alloy wheels for US$2,500 FOB.
If you'd like a little more info feel free to register online at www.skylonexport.com and maybe somewhere down the track you'll start your side-line business.
Cheers,
