get some car magazines...that is what i usually do when got frenz go there. myself never been there. never also in dreams.
as u do not hv time to explore all the car showrooms there, magazines are the best alternatives! cheaper with latest news in new cars. mostly JDM.
but a fren of mine brought back this mag from japan february last year.. inside got the new mira(kancil), new cuore (kelisa), new move (kenari) not to mention lancer wagon(imagine evo 9+wagon), subaru R2, all new corolla (even newer than altis), and new cute civic.
sigh....to describe it is juz endless. but that was last year. i wonder what is on sale in japan now. pls buy some and share with us...and dun worry, it is legal to bring in such magazines.. :lol:
