SA in my place told me that cars ordered from Proton should reach the buyer within 1 month of order.
Only some model like Exora Premium & Inspira 2.0 take longer time.

I suggest you to call the SA & scold him kaw2.Also try to contact Proton regarding the late delivery too.
There were several case of late delivery happened to members here.In majority of case after scolding the SA kaw2 their cars magically showed up after 3 days.
