Toyota Sienta

Hi, is it really hard to find parts and get insurance for Toyota Sienta? Im not knowledgeable about cars. My first car I bought is 2014 used Mirage, and wanted to upgrade to larger car. I found a used Toyota Sienta that I like very compact 7 seater import from Japan. Price is very good as well. But im worried about insurance and might not get parts if I experienced problems... Thanks
