Hi Inspiration, first of all, you have posted this in the wrong section.
But don't worry, the mods will move it for you.

As for the questions, I believe The Oasis should be one of the luxurious condo there in Penang. It has attracted a lot of interests lately as seen on news. So basically, I think most of them have priced in the highest possible margin for the moment.
As for the environment, as you have been in Penang, the road system is not that good there. Until the new PORR is built, I think buying condos in the metro area is not such a good idea now.
Maybe you should consider condos which are going to be covered by the proposed PORR, because of less congestion and noise.
These includes those around the edge of the island.
Anyhow, do lots of consideration and research before buying
