Don't know how much they asking for brand new L410 but you can buy one in a very reasonable shape for 600-700k EUR.
Don't think it is a really good idea to buy a brand new one, you would struggle to determinate a fair aftermarket value for it and this will cause problems with financing. Unless you need it for a short/unpaved strips you better look into Metroliner which is quite comparable aircraft but much faster. C208 is not really an option (at least now) in EU due to the reasons already mentioned in the posts above.
