I was accompanying my friend to hunt around for used car and found one unit that was in reasonable condition.

Car was advertised on mudah for RM36k, and dealer quoted OTR for around RM40k. I did some research online for the insurance and roadtax costs and they are RM1,250 for insurance and RM600 for roadtax.

That means the "hidden" fees are around RM2,150. How much does the usual inspection and transfer of ownership costs though? From what I read here, it was said that the fees are RM30 and RM150 respectively.

So the dealer is actually making RM1,970 without any reason.
