probably because of the stupid consumer perception / belief that if it's good enough for European cars then it must be superior to anything local.
That's kind-of our own stupid fault though, in a way.
The only Euro cars that sell properly here are really good; the average ones they might not even try, and if they do they fail. So the Euro cars people have in mind are the ones that succeeded due to being above average; stuff like last-forever Beetles, hot-hatch heroes like 206GTI's and Golf GTi's, styling & comfort heroes like the original Citroen DS, ur-Quattro's, double-bumper S-Classes etc.
Nobody thinks of a Citroen AX or a Peugeot 207 when they think of European. Or ... lemme think, how about an Alfa 90?
Yet commercial reality means Falcons, Commodores, Valiants, Magnas etc were always sold here, regardless of how bad they might be.
Not that I can recall
anything ever made here which could rival an Alfa 90 for crapness ...
Anyhoo, back on topic; vc commodore makes a really good point, how can tyre sensors work with tyre-inflator goo? Surely it can't?
