Are you sure there is a 2005 Premio. According to my information Premio was upgraded to Allion in 2005. (Corona was remodelled as Premio in 1997-98)
You would have to import one. Totoya Indus can provide you a 2006-2007 Allion. Spares are available with Toyota Indus. Price above 3 million. No resale and on awe-inpsiring thing. Not recommended as a good buy, at least in Pakistan. Consider Crown, Mercedes, Accord, Camry, Prado or Pajero in the same price range.
