We have a lot of assumptions and impressions that are based off what we think we see, but not always based off of actual statistical fact and data. Furthermore, we tend to see a micro-view of what happens amongst our friends and in our region, but we incorrectly assume that it automatically applies to the macro when it doesn't. For instance, "consumers are trading up every 2-3 years" can be a high percentage of certain areas where there are leased vehicles (such as certain states in the USA where people lease frequently), but is still not as high of a percentage in the world as a whole. "Automakers... have invested less in build quality and more in cheap materials" is a huge generalization, for instance, the current BMW 5 series has almost all aluminum suspension linkages and even aluminum front and rear subframes! That's a marked improvement over the past 5 series which had more steel suspension and sub-frame components, and a significant improvement over its other competitors in its car class (the E63 AMG still has a steel rear subframe). So it's not all bad! But yes, you're right, there's a lot of room for improvment! Here on WatchProSite, we try to spread information that is objective and fair and try to not over-generalize too much. Thank you for sharing your thoughts! They're definitely valid!
