I visited a showroom on my way to grocery shopping just now
Aesthetically, overall the car is nice, just lack refinement and polish in some areas, like the aforementioned HU that looked like an aftermarket part.
I also saw the the welding seam on the door, so I could finally understand how an uneducated eye could be alarmed. It is unsightly, but between opening the door, sitting into the car and closing the door, I can't see how it will affect the overall impression of the car.
Therefore, I can only conclude that whoever noticed that must have been painstakingly looking for something to criticize, and the best they could come up with is that weld spot on the door.
I'll reserve the full review after my test drive tomorrow.
