Nice to hear that we are almost relatives:)
Well, for some reasons, Baltic States are viewed together from the distance, but quite different from each other from insider point of view.
In my opinion, Estonia,is probably now more and more closer to Finland and Sweden than to Eastern Europe. Lithuania is the very dynamic and rapidly developing country, but, again, its purely Eastern European by its mentality (and it has both advantages and disadvantages, for example, Lithuanians are clearly better salesmen than Estonians, but they have very different management style). Latvia is something between Estonia and Lithuania in terms of mentality.
From the point of life, I think, big cities are more or less similar, but looks like Estonian rural areas and small towns is much wealthier than its Latvian and Lithuanian counterparts. For some very special reasons. But things are rapidly change better everywhere in Baltics.
Generally saying, for some historical and cultural reasons, people everywhere in Eastern Europe, Baltics and Scandinavia like American cars (and other classics too), respect and cherish it, its very common hobby and always attracts hoards of people. Interestingly at least in Estonia, people don't do big difference between 1938 Packard Eight and Chevrolet Van StarCraft from the Eighties. All considered as US classics here and welcome on every event)
As I told, there are interest for very different vehicles from 90ties youngtimers to full AACA classics. Hotrods and customs are not very popular, most cars are unmodified.
Interestingly, WW2 Lend_Lease vehicles like Dodge WC or Studebacker US6 has very special status in the cultures of former Soviet Union people. Same with the pre-War Packards.
So, regarding classic cars, all three Baltic countries have very active classic car communities. Every country has own strong point. Looks like pure density of classic cars are higher in Estonia. Partially because we are close to Sweden, country where are more classic US cars than anywhere, including the States.
Riga has incredible car museum and very famous classic car events. Again, despite there are less classic cars on road, there are incredible classic car collections in Latvia, dozens of Maybachs, Horchs, grossen Mercedeces etc.
Lithuanians are well known craftsmen, making lot of restoration job for customers from all of Europe.
In this terms enthusiasts of all three country are quite strongly tied, as with the Scandinavian guys too. We have some common swap meets, parades etc. There are all together less than 20 million people lives in Sweden+Finland+Baltics, so we need to keep together.
Some pictures from the last weekend US Cars season opening. There were hundreds and hundreds of cars and many thousands of people around. Very nice event. Especially for not so big City, like Tallinn (appr. 400 000 people)
