Ok. After rather strange difficulties I got some info.

Grepy bike international orders will start within a month. 30% deposit is required after determined a shipping coast of crated Greyp bike to USA or Canada. Rest after the bike is ready to be shipped.

Info came from person who works there and I called him on his personal number to get the info.

Now... Let's say it honesty is the best policy...

Even living in Zagreb some few km's from Rimac factory was not any help to get someone pick up the phone at Rimac factory Greyp department. I called from my mobile phone and my office line. In the morning,  in mid day and in early afternoon. Nobody picked up. Not that I am making big fuss about it but... It is from my very personal point of view not a good sign... Over 80 people are working at Rimac factory.  Is it a too much cost to hire some young lady just to answer the phone?

I am a Croat living in Croatia.  Rimac is a new name in car manufactures world and he and his company need to learn a lot about small detalis. Having a decent costumer service support is one of them...
