i scrapped my wife's car today at the scrap yard.

here's what i did (no outstanding road tax, car was paid for in full with cash):
1. GET YOUR TPIN
a week before i flew into singapore, i logged into onemotoring to request for a transaction PIN.
it is under "My Account" then "Transaction PIN" - poke on from there and a physical PIN will be mailed to your registered address.
you can also update your personal details (including your banking details for LTA to credit rebates to you after de-registration) before requesting for a PIN. it is under "My Account" then "My Profile" then "Update Owner Particulars" (at the bottom).
you will need to bring this PIN mailer to the scrap yard.
2. FILL THIS FORM OUT

3. ID. you will need to bring ID (either NRIC or Passport).
if you have outstanding taxes, they would need to be settled at some point. i'm not sure when.
if your care was under HP, you'd need to check that there is no hold placed on it. do so through your bank or LTA (this was info provided by the scrapyard - i asked for the purposes of this post).
i went to the first scrap yard on the list of 4 provided by LTA (within the first link in this post). this part of the post is specific to the scrap yard located at 26 Sungei Kadut St 3.
do not drive into the scrap yard.
ask where to park - they will point you to the end of a row of parked cars - try to park where they point to.
walk straight into the scrap yard, and you will see a little window with a posted sign that says "SCRAP CAR OFFICE" (or something to that effect, a white sign with big red letters).
if there's a queue, then you'll have to queue. otherwise, submit your paperwork (completed form, PIN mailer) and soon after, someone will go check your vehicle for the chasis and engine number. you may be asked to accompany the person doing the checks if they have no clue which is your car, or if you drive an unusual car that they don't know how to find the chasis plate/engine serial number.
if you've parked your car farther away (like i did), then you go drive the car to the guy and he'll direct your car into a suitable position.
after checking, this guy will tell you how much in scrap metal you will be paid for your car. eg, $90. you will then go back to the little window to get your paperwork processed.
after 5 or so minutes, you will be made to sign a few sheets of paper, and be given a print out that says your car has been de-registered. you will be handed also some cash (scrap value), your PIN mailer, the bottom bit of the original application form, as well as a print out on how to encash your PARF/COE rebate.
if you've already updated your bank account information, shown earlier in this post, you log back into onemotoring and click on "Ownership" then "PARF/COE rebate" then "Apply to encash rebate" - i haven't done so, so i'm not exactly sure how that works just yet.
apparently you'll get your money back through direct credit into your bank account, or, if you don've have one, a cheque in the mail (i think you'd still need a bank account for that, so direct credit seems the quickest).
i will update this post when my wife has decided if she wants another car.
my wife got to drive her car until the very last day, and got a few hundred bucks more than the highest quote a car dealer gave her (and they wanted her car 10-14 days earlier). granted, we both had to take time out to go there (as she had to drive me home), the process quite easy and straightforward. it took us about 20 minutes - including wait time as there was a short queue of people wanting to scrap their vehicles ahead of the long election weekend.
i hope this helps. i believe it would be a similar process at the other 3 scrap yards.
to the OP's questions: they don't care what condition your car is in. the engine serial and chasis number MUST match LTA records.
