If you say you buy want to retire peacefully, then you're wrong. This place will be like Subang Jaya so still you can't retire in peace. To retire in Peace you need to buy prop outside KV i.e. at Genting, Seremban, Manjung (WCE Access).

But if you want to conside KV Area, you can go with Gamuda Cove but I highly suggest you go with Serenia by Sime Darby. I myself bought Gamuda Garden which compete with Elmina, all I see is that Elmina built quality and land space is way more better than Gamuda. But no doubt in terms of lanscaping and privacy Gamuda so far did a good job.

Also please consider that area is flood possible area? South KL always flood hence why I choose Gamuda Garden haha. A lot more factor you need to consider. Take your time to survey, don't follow your lust.
