Langkawi cars r allowed to be used 90 days on mainland , not 1 month . Also , after 90 days , there's a fine until you go back to langkawi , RM150 a day or what , i forgot . And of course there's a bond , " cagaran " b4 it can be brought out to be use here if u wanna take it out the minute you bought it b4 the grace period . Bond in terms of an FD but the dept have the right to take your FD if u fail to come back . What most supercars do is make use of the loopholes to avoid tax . They pay their fine since it's cheaper then paying tax . Example , tax difference of 1 year for an Aventador is around 200k , meaning if u pay RM700k in 2013 , u only pay RM500k in 2014 . That's excluding depreciation of car value . And lastly , road tax difference between a Langkawi cars and peninsular cars . Then that's where u get all the G1M supercars running around .
