It can't come in unless you figure out a way to get around the three year old rule.
These are the official rules from LTA... let me know if you figure a way around them.

And, you may want to think about the cost. Automatic $10,000 fee for a used car. Then 110 percent of vehicle open market value which includes the vehicle, all shipping, and inspection fees. Don't forget 20 percent customs duty and 5 percent GST levied on the whole mess. Oh, and then you have to buy a COE... around $20,000 right now.
So, you bring a car with an OMV of $20,000... you will pay about $60,000 to register it and have a permit to drive it... and you still have to pay for shipping, inspection, etc.
And that's if the car is less than 3 years old... otherwise, forget it.
