I've seen this question quite a few times here and there, just thought ill do a short step by step write up to help those who need to DIY cause runner fee's are RIDICULOUS.

1. Buyer and seller to discuss who will pay for inspection and change of ownership fees.
-Inspection Rm30
-Change Name - Rm150

2.Seller to bring the vehicle to puspakom for inspection with geran/registration card. Request for a form at the counter. Complete inspection and collect the slip/result.
B5 - if new owner buys with cash
B5/B7 - if new owner is using hire purchase/car loan, once done provide approval slip to bank and bank will do name transfer on their side, you pay the bank rm300-400 depends on the banks...they call this transfer fee if I'm not mistaken.

-please remove your tint if it's too dark yourself by going over to an accesory shop, they can charge between rm30-60 depends on car/place etc.. if not puspakom guys will just tear it off and leave the gum all there or just fail you.
-some are even open on saturdays for those who are busy working during weekdays. can check out their site

Update:
3.Proceed to JPJ for change of name request with geran and all the documents above., request change of ownership(tukar nama) document at front desk. Fill form of new and old owners details. Obtain que number from front desk and proceed to counter for IC and thumbrpint verification for both new and old vehicle owner.

4.If one party is out of state, they can go to their respective JPJ branch and complete the procedure seperately.
For those who cant go to jpj directly:

Runner fees for inspection can range from rm80-rm150, and change name rm300. for those who dont have time, can use this services. For those who needs special request due to punched engine number, mounting modification, no approvla for sunroof etc or aka special case, you have no choice but to bare the fee's of a runner which is going to cost definitely more than Rm150 for special case. I even heard of Rm1k for this kind of situations.

Prepare your geran, photocopy of IC buyer and seller and hand over to runner. He will also need the original signed copy of the forms mentioned above.

ADDED:

For those who want, can aslo call puspakom 03-20527474 and schedule an appointment 3 days in advance to come over to your house and perform the inspection Rm100 service fee+rm30. However only certain branches can offer this services, so check at the link above or contact them.
ADDED - Hire Purchase

Your quoting a 9year old post.

a. If does not involve loan from financial institution, then just change name @ JPJ. Assuming vehicle is already paid off & released by bank.
b. Ofcourse its possible to fail, thats the point. Fail = not fit to transfer ownership.

That is outside of scope of puspakom & jpj, its entirely between current & future potential owner.

Anyway, unless tint is out of spec, failure in regards of body (aka, kereta potong & sambung for example) cannot be rectified once fail, as its illegal.

If engine number no match, can just endorse with proper documentation (they will test more item like brake force, headlight, undercarriage, etc)

The point is, cannot change ownership if fail puspakom, and not all failure points detected by puspakom can be rectified.

If your own car, you would know best if any major repair to body or change of engine was performed.
