Thanks a lot Sam, that was very helpful and concise.
Yes, I did carry & fill the PDI checklist.
Today's update: We went to see the new car, this time there were no panel gap issues on door, bonnet etc. Also, I located 3 small scratches (about 0.5 mm each) but it was ok. But my wife pointed out that the front speaker (driver side) cover was not fitted correctly, on all other doors it was perfect but here it was bubbled.
When I asked SA if it could be fitted, he said that was difficult and cannot be rectified, when pressed harder, I got to know that the door had to be removed or some sort of major work required. I still tried to see if it was just some fitting problem but looking further seemed the plastic net size was perhaps more than the actual space that was the reason it had bubbled.
Other things noticed:
1) ODO reading (with H) was ok - 18Km
2) Front tyre threads were gone, rear and spare tyre threads intact
3) Tyres read 2311 Goodyear --> probably June 2011
This time around I was ok with the car (even the speaker cover issue) but my wife objected and we left without taking test ride
