@hungama007 Grande is not a problem, I got mine within a month, it is the rest of the models, and contacting Toyota is hopeless, they write you a lovely email and nothing really happens, its the dealers who are doing insider dealing.
When I upgraded from 1.6 to Grande to save time and money, the dealers were themselves unsure what to do. This caused a 2-week delay because as per Toyota policy for an upgrade the old order gets cancelled the money takes a scenic route through the banks and then another order no. is issued, talk about modern business.
