  • VGIS (Variable Geometry intake syatem )technology not only increases fule economy but makes engine powerfull as well and hence results in increased fule economy in longrun ,hence it is advisable to go for VGIS engines. Used car of optra 2004 model is a very good choice considering maintainance, comforts of interiors,stylish body design and fantastic fule efficency of average 12-13 kmpl.
