Many writers on car magazines have this pro-German/anti-Jap viewpoint becasue they grew up in the late 70s to late 80s lusting after many of the desirable German cars of that era, like the VW Golf GTi Mk1 & 2, the 2nd generation BMW 3-series, etc. To these people, a Japanese car is something your granddad bought because it came with a radio and heated rear window as standard, and didn't go wrong every Tuesday like an Allegro or Mk2 Escort, which exactly were the selling points of Jap cars of that time.
I'm just into my 30's and my view of Japanese cars is completely different. I remember Colin McCrae thrashing a Scooby through a forest, those blalistic Accord Type R's, etc. These were the cars which grabbed my attention in the mid-to-late '90s.
