No offense intended but since the 6694 has a relatively low entry-level price point, its value cannot run very far off .... they go for anywhere between RM6-9k retail. That might seem like a huge 50% diff, but in absolutes, it's only 3k between the lower & upper limits.
If you want to post some pictures here, I am sure there will be a few forummers who are happy to help with their input.
Alternatively as you already mentioned WW in Subang, they do charge a small fee for an official valuation. You might also want to check their websites or even Mudah to get a feel of rough market prices.
Good luck.
