As Promised:

Seat Belt Clip; just make sure that the seat belt buckle is fits snugly behind the plastic clip.

The foot sils become prone to rattle, as one often steps on it while getting in and getting out. The best solution is to make sure that the white colored plastic clip on the reverse of the plastic panel is packed with a foam insert, similarly, the holes should be covered with a foam sheet, foam insert is put in between the plastic panel and the car's weld joint.

The plastic cover, which prevent water front splashing onto the alternator, exhaust manfiold joint etc, rattles a lot. It is best advised to either stick the black pastic part with the bumper clips, or hold it tight with a zip tie. At times, the number plate too rattles along with its horizontal large plastic part (on which the number plate is mounted), and the one behind the bumper.

The clip which holds the bonnet rod, fits loose. It rattles like hell over paver blocks. It is best advised to back it up with a foam insert after pulling it out, or wrap an insulation tape in the gap, thus holding it firmly.
Pic 5:
Driver Side door sil is the first one to rattle among the door sils. It is best adviced to follow the procedure as described in pic 2
Pic 6:
This is the plastic panel under the steering wheel; the quality is real bad. Unfortunately, due to problems in the central locking wiring, it was removed 10-12 times, due to which the plastic clips on the reverse have lost their shape and keep rattling repeatedly even over smooth roads. It is best adviced to insert foam strips in the holes which hold the clips, along with placing a foam strip as shown in the pic

As a test, you can try tapping it, or moving it to and fro, you will hear the rattle! One needs to pull out the plastic garnish, once done, insert a foam strip and gently push the clip on to the garnish; thus holding it secure. You can now push the garnish into the body.

The glove compartment too develops some amount of rattle after some amount of time! It is best adviced to insert a foam strip which ensures that the glove compartment doesnt shift from side to side (on the hinges); One should also use foam tapes the side walls

It is best adviced to have the metal clip, which holds the glove compartment, covered with teflon tape, or with masking tape. Initially, it makes the lock a little tight, but eventually closes smoothly.

The plastic garnish, which can be accessed from outside, and is present at the end of the A pillar to fender joint, makes an annoying high frequncy rattle while moving on paver blocks; it can be heard inside the cabin even when the doors are closed (obviously while driving) and when the windows are rolled up. Place a foam insert between the garnish and the body or pull it out, and make sure that the plastic clips fit properly.
Another areas, if applicable, are the plastic mesh under which one can place 4 inches speakers. Make sure that the speakers screws are tight, and if needed, one can put small inserts of foam tape on the sides and then fit the mesh over it. Dont worry about the glude residue of the foam tape, as it comes off easily with WD40.
I shall keep updating this thread with stop gap solutions for fixing rattles; hopefully with better quality snaps next time! I did not find the time to charge my digicam, and then transfer it to my laptop.

I hope this thread proves to be helpful, not only to A-star owners, but Swift owners who may have similarities in the parts, or others.
For now, the only rattle present in my car, is from the steering rack! I shall get it fixed, once it becomes unbearable. Frankly, I am tired to go to the service centre yet again.
