Hi, and welcome to the forum. I hope you will get used to having the wheel on the wrong side of the road, I know I wouldn't
But you are absolutely right about the price in the Netherlands. When I was considering buying the Z three years ago, I was once transferring at the airport in Amsterdam. I had some spare time so I browsed the official Nissan webpages and, naturally, it redirected me to the Netherlands site.
At first, I could not believe my eyes as the price was more than double what the cost was in Czech at the time. It was nearing the price of a new BMW M3. I think you've got something seriously wrong with taxes
