weird mean? over cranking sound? all depends on luck bro...but most of the time if the weather is really cold then higher chance will get.

the overcranking sound caused by OWV issue, some owner has change at SC but still have it.

for super fussy type, this is not normal and keep fucuking the SC.
for cincai type like me, i am okay with it as it happen occasionally(less than 10 times or 5 maybe,2.5 mth car) especially after rain in the morning.

if ur sis need the car then just go for it as we dont know when proton will fully solve this problem and like i mentioned earlier, its all depends on your luck.

else just go for more reliable car as sometimes its a headache for fussy type ppl 

*i would recommend ur sis to choose preve bcoz hoh, we need more gals member
