No, I have never put a modern car together and you haven't either.
However , millions have been put together without any problems. And to the other moron who commented on my post, you call your new car taking a dump @ 60 on the freeway a bug? Now who is delusional. I would call a bug the dome light not working or something minor, not your new car taking a dump on the freeway at 60. Obviously you have been raised with the expectation of new things having problems or breaking down, maybe you are young. I was raised at a time where when you bought something new, you had the expectation that because it was new, you would not have any problems. Isn't that why you buy new? Who here buys a car expecting there to be a problem ?
