Bro,
I always go to MK Auto (used to be in Kolombong, the one that Petrus said near SK Dynamic). They just moved to Jln Tuaran bypass, just after the inanam traffic light.
RightPart recommended SK Dynamic, as they are at the same raw of shop building, but the workshop is cramped. Yes, RightPart is one of the best & cheapest Conti parts shop. Bought many parts for my E46 & C230K there. MK Auto can also order parts but slightly expensive than RightPart, but they give discount for labour charge.
If you just buy the part, go to RightPart. If need installation, go to MK Auto. My friend recommend another workshop, will try next visit. So far, i'm satisfied w MK Auto. They are all in Inanam/Kolombong area.
I dont recommend 1-Garage, although they are walking distance to my office @ Sadong Jaya. 2 of my cousons had bad experience with 1-Garage.
Maybe we can hv TT @ KK ;-)
