Purchase via the overseas websites, even if you tack the usual $50 shipping cost from the US on top you usually come out ahead. Same issue with BMW Australia. I can get 99% of the parts I need for my E30 from the US - usually at 1/3 the cost (the remainder are RHD specific parts). I bought 300 bucks worth of parts from the US and got them within 2 weeks. Compared to BMW Australia who quoted close to $900 for the same parts and up to 2 months delivery on parts from Germany, the shipping cost was a massive saving. Sometimes the parts are marked up 200% over US costs. You can do this with many US Honda suppliers too,
