The ferry to and from Finland across the baltic is pretty expensive for cars, no matter you come via Stockholm or Tallinn. So my bet is that the biggest expense would be ferries, then fuel, then everything else in Finland. We're an expensive country, sorry! Actually you're reading my thoughts there. Have already been thinking, for many years, about a roadtrip to the ring but what would make it even cooler would be to try to organise an official Civic5 euromeet at the same time? I'm thinking about summer 2016, gonna start a topic about it at some point but just to let you know! I think it would be hella cool.
