Can the golden numbers such as single digit and double digit numbers be tendered for via E- bid ?

Check online for those companies that sell number plates. They might hv what u are looking for, registered on a bike.

Possible...if you die die must get that number, put in a high figure at the very last minute to ensure 99.9% success.

I dont think so, both also you need to take up. The tendered amount will be charged to your card.

No need, in the event of a successful bid, you just need to give a copy of the
JPJ letter (PDF emailed to you) to the SA when you purchase your brand new car.

The number of digits would be rather long, i.e. WX 1234 X
Not preferred by most local car buyers.

No, but from another similar setup. I let my SA handle all the transactions with them.
