Hey by the way in Jamaica they have RHD Toyota's & lots && lots of Altezza's (they call them Baby IS300 or Baby Lexus) and they order parts for them all the time from what I hear....
You *could* give them a ring down there and see if they are willing to ship you parts....its not even 3 hours flight from where you are at now. Would even be worth taking "vacation trip" down there to get parts & party it up.
Try your best pigeon-english....
Welcome to Toyota Jamaica

Welcome to Toyota Jamaica
this is how I did it with the Canadian dealer with limited success....not much JDM for them, from what I understand is that Jamaica is much more JDM
