"Having a bad tranny in a new car is not enough reason to call a car crap."
Having a car in the 1970s rust out isn't either, but it doesn't stop some from having a permanent hate.
Personally, I think having a transmission go after 4 months on a new car IS a reason to call it crap; but then, I once got a Neon as a rental with 100 km on it, and the transmission went kablooey 10 km after we left the airport. I still think Neons are crap.
But then again, maybe your definition of "crap" is different from mine.
