I thought they don't use the brand "Acura" except for the US market?
I looked at their website, and they list telephone numbers for both Canada and for Europe in a Flash presenation at http://www.acura.com:
Acura Canada: (888) 922-8729
Honda Motor Europe, Acura Division: 01753 590590
I don't think Honda uses the brandname Acura in Japan (at least yet); here's what the Wikipedia currently has about the Acura brand:
Acura is a brand name used by the Japanese car manufacturer Honda in the US, Canada and Hong Kong since March 1986 to market luxury automobiles and near-luxury vehicles. The brand was introduced to Mexico in 2004 and the Chinese market in 2006. It is also planned to extend Acura to the Japanese domestic market in 2008. With the Acura brand, Honda is credited with being the first to tap into a market for luxury Japanese cars outside Japan. Before Acura, automobiles from Japan were primarily economical and were seen as reliable above all else.
