I worked in the automotive stamping business for most of my life and tool & die maker before going into engineering. I laugh about people concerned over the gaps. It does not make the car run better, get better mileage or a safety issue. It is a vanity thing. Give me the quality of the 70's with those prices and I will be in heaven. I could buy 10 new cars for the price of one.
We stamped parts for BMW, Toyota, Ford, Nissan, Mercedes, Chevy, Dodge and others. We also made parts for lawn mowers on the very same equipment with the same quality standards. I have seen new BMW's with horrible alignment between the front fender body lines and the door. When they first made their X5 the bodies would stretch when pulling a trailer and the battery box would drop down in the rear. A quick application of some band aids fixed the issue.
An automobile is not a piece of art or a thing of perfection it is a form of transportation. So if you want perfect you will have to pay someone probably $75,000 to take you car and weld up gaps and massage everything to as good as they can get it but I bet I can still find something not perfect. It probably would not bring half that to sell it. No such thing as a perfect car.
Great discussion get to understand what makes members tick.
