We are right on the main road in Sai Kung town just across the road from the Police Station (at the Sha Kok Mei Road junction).
Sometimes it is not that easy to stop on the main road so may we suggest the following, either:-
(1) just turn into Sha Kok Mei Road and stop there on the bridge and walk back around the corner (a few seconds) or even drive up a little bit further and park in the metered car park in Sha Kok Mei Village itself which is only about 80 meters further on, and walk back (2 minutes), or
(2) park safely in the road opposite the Police Station entrance (lots of room - easy) - and walk back across the main road (a few seconds), or lastly,
(3) park in Sai Kung town itself and walk back through past the Police Station and cross the road to the showroom (3 minutes).

Alternatively, and whether your are driving or not, we would be most happy to meet you in Sai Kung town itself, say, at the sea-side Bus / Mini bus terminus or even outside McDonalds (or anywhere it suits, for many people,, probably the easiest)

Taxis offer the simplest way to visit Sai Kung and which will not cost more than about $200 / take about half an hour from town. By public transport, the easiest ways are: (A) go to the Hang Hau MTR and catch the number 101M mini-bus direct to Sai Kung ($7.40) or (B) go to Choi Hung MTR, go to street level via exit C2 and catch the number 1A mini-bus direct to Sai Kung ($7.50). Both mini-bus journey times are only about 15 - 20 minutes.
