im not going to be an apologist... i lemoned my 2010 after 60+ days in the shop, and have a 2012 that has never spend a night in the shop.... I dont really give a crap one way or the other. I have multiple cars, I get loaners...
But what does a '5' mean versus a '0' or '1'...from a "I bought one, what can **I** expect??
Is a 5 mean 5% chance of service in the first year? And 1 is 50%?
Or is 5 0.5% chance and a 1 is 2%?
People get tied up in ratings, but what do they actually mean? Again, not to minimize, but what might a buyer expect for their ONE copy they purchase?
Keep it as simple as possible...but no simpler.
