Trade in during new car purchase is the simplest but lowest value unless cold new model eg Nissan, their salesperson might offer better rates.

Sell yourself need to deal directly with buyers / agents/ scammers - need to meet away from your house for safety purpose somewhere public.
Then need allocate 1/2 day get Puspakom cert after tearing away front and side tint.
Lastly go JPJ to execute transfer AFTER payment deposited best together w buyer.

Easier to drive to Carsome or Carro get quote, then surrender on the spot if price is right.

Dang. After Puspakom, no need go JPJ liao?
