Some myth on Pre-registered cars
1) Resale value is lower compared to an unregistered unit
The resale value is very dependant on the Year Make and condition of the car at the point of sale, not so much on the past and number of previous ownership

2) Warranty not valid
The warranty shall be transferred to the next owner and valid for 5 years from the date of registration

3) Plate number registered cannot be changed
Usually, a nice number has been chosen for the plate number for the car. However, it is still possible to change the number thru a number interchange process but some cost for the interchange shall apply.

4) The pre-registered car is a test drive / showroom car.
In this specific case, the cars are NOT , they are basically brand new physically with mileage clocked only from the testing done at the factory, prior to shipment to the sales outlet.
