Your point 1. may be correct,but he got all the certificates from Japan to prove it otherwise.Then the Yaris I bought was built in Japan and imported from Japan.I have all the documents.True, bad driving habits play a role there.But in this case, my cousin is a careful driver.He hardly exeeds 60km/h.On the other hand he drove his car mostly on good roads,while I drove my car on poor roads.When I told this problem to a tech guy at Toyota, he said that the cars that they import to Srilanka are made to suit our road conditions.For example, he said that B/N Yaris has a 47% stiffer suspension system than the JDM,stronger plastics which could withstand very high temperatures etc,but our people do not care about such things, instead they ask for DVD's and winker mirrors.
