I have to agree that the H3 has some advantages offroad to the H2. I've had both the 2 and 3, and the width and size is a major factor on some trails for the 3, but for comfort the H2 wins hands down and having driven an H1 and been a passenger in two others on trails go with the H2. Since you live in Europe with its narrow roads the width of the H1 is going to be a major factor if you drive it every day and getting parts for your H1 will be a boon to UPS or FedEx. H1s are maintenance intensive as has been stated before.
This article is about an owner in Tokyo with an H1, but some of it would definitely apply to you
