I am searching for a Toyota Corolla GLI (in 1.2 Million PKR budget) but confused with models specs like vvti, dual vvti, cg vs petrol.
Can some one please mention about the major differences in different year models of Toyota Corolla GLI ?
perhaps a comparison?

Like 2009 model specs difference vs 2010 or 2011 or 2012 or 2013 ?
