My car history includes Fords, Mazdas and Skodas (VW group), so nothing Japanese.
(Edit: Apart from the Mazda.... Obviously.....)
I don't know if the parent was talking about major crashes, or reliability issues, 2 weeks in the shop would be my limit of acceptability for any car, a month, I'd be asking for my money back assuming it were a reliability issue. And multiple 2 week waits or a month wait, I wouldn't be buying from that manufacturer or dealer again, whatever the reason.
Is that my European point of view? have I been amazingly lucky?
