Just wondering, where in Thailand are you planning to go to? As the hatchback body style isn't offered in Thailand (Not even as a JDM import. Most South East Asian markets have a preference for sedans over hatchbacks.), some Corolla Altis parts will fit, while some won't. General parts like bulbs, badges, LED wing mirror housings, HID kits (Not headlights or taillights, the 2001 - 2007 SEA Corolla Altis have totally different front & rear ends.), gear shift knobs & stubby antenna should be fine. I'm not an expert on the Corolla Sportivo, but I'm guessing that some Celica engine parts may be compatible as they share the 2Z-GE. You might want to ask people in Altis-Club & Wish-Mania (I know there's one English speaking member from Bangkok on W-M.) as they would know better.
