To be fair to myself OF1, since I got my confirmed build week of 32 over 7 weeks ago, I called and mailed a grand total of zero times. I mailed my dealer Monday just to check it was going into build, and was told it was. Today, I called VW just to check, because I have to plan some travel for a few days on business in September so wanted to try and objectively work around it. For me to get told that it is actually NOT in build goes beyond any level of crap customer service I had in the past.
Having said that, I generally agree with what you are saying, and there is no way I'd change for a car I never considered before "just because". Though, as Bear pointed out, some people are being hit financially by not getting their part-ex secured, and they made that decision based on poor information at the time.
