Just right hand side opposite to Yellow Bus, the "Liu Suk Car Park" will be more cheap. $40 may be for 12 hours. Even the "Fu Tai" is a bit far is approx. $50 per day, and they provide car delivery services to Yellow Bus Stop. I am not sure the price, but will not too expensive.
The one strict opposite to the Yellow Bus "Kwun Lan" will be more expensive due to the car park belongs to the golf club.
