Whatever happened to E.Deming who brought Toyota back to a car market contender? When Quality Control and Management were synonymous with Toyota? How does one find out what features are on what and what model is what nowadays? I bought my first Prius, a 2010 V, in August of this year, which was rear-ended and totaled by a drunk driver 3 months later. Today I bought a 2012 Prius v (lowercase for the Prius v wagon. The 2010 used uppercase Roman numerals for model designation). After I sat with the tech person, and signed all the papers, I discovered that it did not have Lane Keeping Assistant. I was told 'too late' to wait for a 2015 Prius v my car was now another step down in 'used' plus they did not know if Lane Keeping Assistant was included with that package, now which car had this feature. This feature was a huge plus for me when it came with my 2010 V. I have spent many hours online trying to figure out what car had what on Prius, C, Personal, 2, 3, 4, 5, whatever. The sales people can barely explain. The online lists leave many things out. This seems to be obfuscation for purposes, what, for the anti-environment lobbyists? I cannot see why they would name their cars in such a confusing way, plus change the features year to year without leaving a buyer to know what they are not getting. This seems a far reaching effort to make a great car a Fail. So I go onto the Toyota site to "Build a Prius"; I go to the 5, and there is only Two, Three, Four, Five and Persona. The 5 (or is that a v?) does not state the colors that are in the new brochure for the Prius v. So that is not the 5? One begins to feel bamboozled here. I am sure this has been mentioned before, but where is the response from management. I need to trade this 6-hour car in for a Prius that has a LKA.
