i am dirving proton iswara sedan 1.5A year 2000. So far my power window is working perfectly. I got no issue with the car except for few parts that are wear and tear. For the price of the car, i guess i cant complaint much.

Improvement i hope to see from proton;
(1)Sound proofing in cabin area because driving at high speed will eliminate my radio/cd sounds. Not expecting them to be totally sound proof like merc but at least half of it
(2) rattling sounds from various place which i do not know where from.
