Buy a cheap car yet wanted to be served with the same level as Mercedes, Porche, BMW, Jaguar...

No product is perfect. Sometimes some minor issue, just ignore it. Like a little bit of sound here and there.. just let it be.
It's a PROTON for God's sake.

Just like buying a BATA shoe. There will be poorer contruction compared to shoes hand-made in Italy. So, you gonna go back to BATA and trash em for their shitty quality? Then demand to see the Manager and whine and whine... why la this shoe not comfortable, the cutting is not perfect etc.

Want better quality? Buy the REAL Lancer. I believe Lancer quality > Inspira.

Just my 10 cents.
