Nothing much to take note, just make sure there's no unnecessary charges like topping up your wiper fluid or something which can be done yourself. Remember to state any problems that you face with the car so that they could rectify it for you.
AC Fan? You mean the radiator fan? P2 cars radiator fan are known to be loud actually. Sometimes from far when u hear it , you will know it's actually a P2 car coming near lol.
Updated! Welcome to the Club
Hi dares Not sure what SC that I could recommend you though but before this when I was still driving the Myvi. I used to send to the Desa Tun Razak Branch. Not a 3S Centre though. The service there seems fine and acceptable. But if you compare when I sent the Preve to the Desa Tun Razak Branch too (Proton SC beside P2 SC), not sure if its only me..I actually find the person that attended me was very friendly compared to the P2 one. He even apologized that it took 3 hours as ECU and 3 Power Window Regulators had to be changed. So yea, that's my comment about it. Or maybe you could see if any other members here has a better SC to recommend you

got my myvi last weekend..
booked on 9/2/13.. but then need to wait for the car to be shipped to KK..

Variant: 1.5 SE
Transmission: Auto
Colour: Ivory White

so far, the fc is only 10.5 km/l.. but then i've only driven it for 350km..
driving it back home from KK to kudat, with speed only 80-90, was a bit tiring though.. huhu
