Hey there,
Sorry cause i can't help you much cause i imported my 8 from Australia. But i would like to give you a good tip. I just knew a friend who bought a recond version from Japan thru local dealer. It has Mazdaspeed bodykit, Mazdaspeed rim, Abflug exhaust, which sounded so similar to the RX7 toned and other goodies. Cost below RM195k. But if you aim for a new one, NAZA, Mofaz and Ming Heng are obviously your places to be.
Cheers
