are you referring to JEN WEY MOTOR? I have been there couple times, and always deal with the malay chap there, its been a while hence forgot his name, but he speaks well in chinese

He had always been very helpful and recommends on where to get certain parts cheaper.

I own an older version of Optima, love it, K5 is in my list but not now, due to my other financial commitment. I wouldnt think twice to go with Optima. Even my model I get 13km/L on hghways.

SInce I'm not bound by warranty, i service my car at a known trusted shop and buy my own parts from spare parts or from LYN sellers here. The parts price are way cheaper.

WHenever I have any typical Kia issue, I go to SC to diagnose, nowadays, I bring my car to Hyundai SC. Found a trustworthy guy in Sunway

It will be easier to read and discuss if every feedbacks based on either km/L or L/100km

generally if you median drive ( not the hard acceleration type); you should get about 10km/L for city and 13km/L for highway.
basically your speed doesnt exceeds 110km/h

hope that helps.

even if JPJ approved, it may not be Puspakom approved! Dont know why its not standardized!

Its programmable at ECU level, take it to SC and get it programmed. There are lot of things that can be set, talk to your SC guys.

Some of it can be done by user as well, such as aircon; but there is a process like number of times you need to depress the aircon combination button (its been so long, forgotten now)
