Even my mother's new FLX welding is ok.
How come Preve's welding like this?

@FrostLance
But welding in 2nd picture is really bad.It looks like the welding cracked already.

@figuremeout
Some Proton Sales Center do sell the car that they keep as model.So no matter whether it's display model or model to be sold Proton should have done better with the welding.

If you're unsatisfied with the car that you get you can always refuse to sign the agreement when you go to pick up your car.Proton should give you another car.
