My experience with Komoco was mixed.
Initially before buy, v nice. Bought, still nice.
Then when it came to delivery, problem lai liao... SE was noncommittal initially, and until i pushed for a firm date as I wanted to sell off my approaching-expiry car (since Komoco doesn't do overtrade). After shipment arrived, started registering, then she confirmed a range of date 24-25 Apr (Mon-Tue). i had bought and secured COE way back in Feb, and later shared my experience with a bro here and he bought it one COE round later. Ended up he got the car (same model/colour) before me. I was asking my SE and she just said it's their scheduling...
In any case, i arranged to handover my car on 26 Apr, giving one day's buffer, and on 24 Apr, she told me it's nowhere near and likely to be end of the week (27 or 28 Apr). I was so upset and almost scream at her, but kept my cool. Kept on pestering and i could sense from her msgs that she's also buay tahan me already. But finally managed to deliver the car on 26 Apr, just after i handed over my old car.
So it became not so nice anymore.
Then later I found that the HP 2-channel car cam shows left/right inverted images/videos for the rear cam. When i brought up, they didn't even know of it yet. Complained for 3 wks, then the initially very enthusiastic quality service manager said nothing can be done, and they will feedback to management, and seek my understanding.
Became very not nice already...
