they don't have a list of approved cars but they have a list of
documents etc that u'll need to get the car approved.
you'll need to import the car first, then bring it down to LTA for
homologation, so that's the risk you're gonna have to take. But as
long as the car is new, roadworthy, abides by the noise and
emission standards, i don't think it'll be a problem.
good luck.
