jayking,
did you get the manual variant? anyways, what you can mod without compromising the warranty would be to dump in a K&N drop in filter element lor...since they've got a no-void warranty claim. if you're daring enough, head on to TiTANs to change your current suspension, all you need is to change the front to coilovers and the back you can't do much but play with the springs i guess, cause you're running a torsion beam setup in the rear correct? what else...hmm, change rims, but i'd suggest nothing over 15"...actually that's more than enough...but if you want performance, stick to 14". get better tyres, BFGoodrich or yokohamas are good. erm, add in some semi buckets from sscus, i think about rm490 a piece plus you could trade in your brand new savvy seats for a rebate! :) change to Q8 Oils during your next service, i think after 5000 km right? upgrade your brake pads to stoptechs or mintex...around 100-200 rm ones will do fine. anything to do with your engine shouldn't be touched yet (ie. exhaust setup/cams/engine internals/bolt-on turbos if any) because like what others said...the warranty :D
drive the car first, get to know it better and slowly upgrade from there. don't one shot dump everything in la, cause then you might not be able to cope with the upgrades.
hope this helps.
