My 2 cents.
Autocar Asean - So, so. Can be a bit biased at times. I buy it sometimes when it features something I like.
Evo Malaysia - Thumbs up from me...for the UK articles. The local ones are just ok and like Autocar, can be biased. I buy it every month.
AsianAuto - Worse than the 2 above. Used to buy it, not anymore.
Hypertune - Used to love it. Going downhill ever since. Maybe its just me. Too much ads these days, as well. Still buying it, but seriously considering stopping.
Traffic - Not my cup of tea. If I want photos of modded cars and lists of aftermarket parts, I'd surf the internet. Actually, Hypertune has this same issue as well. Bought several and then stopped.
Motortrader - Rather visit Motortrader.com.my.
