Thanks Kenneth for the hospitality during the three visits.
Sent my car in last week for the $158 package. Found the engine smoother and more responsive after the additional additives.
Unfortunately, aircon was down. Sent in again today for pipe/hose replacement as gas leaked. Finally done and can enjoy my aircon again under this super hot weather.
Overall experience with Kenneth and his team was excellent! Kenneth is patient with me, mechanic is experienced and price is reasonable.
Kudos to AF Motorworkz!
