Heinrich, you're absolutely correct.
The brand or model of a car doesn't always warrant good reliability.
Sadly, only after a few years later, we would find out how good/reliable a particular brand/model is.
I would not compare an Accord or Camry with a GTI anyway, since they're domestic (locally made here in the good old US of A).
I don't want to start a FW, but you're comparing apples and oranges - At least your GTI is an import (Mexico or Brasil?)
A better comparison would be against an Acura TSX or Lexus IS. I think you'll be surprised at the result!
Even the cheap Scion xB would be a fair comparison since they were made in Japan.
That aside, most Corolla here are made locally. (Fremont, CA - very local to me anyway)
