I am Malaysian but living in Brisbane, Australia currently. I do go back yearly and recent December I certainly noticed more Audis on the road with A4s the most commonly seen. Only seen one A5 to date in Damansara Jaya.
Needless to say that car prices in Malaysia are really crazy, I really respect those who are fortunate enough to own an Audi (or any other non-Proton car for that matter).
FYI, prices in Australia aren't that great either compared to the UK and US. We have some ridiculous Luxury Car Tax which jacks up the price a great deal.
