I am planning to purchase newly launched Toyota innova New

I am planning to purchase newly launched Toyota innova New cng petrol, vehicle in Goa. Please advise if this model is available in Goa and if not which is the next option. I would much appreciate if you could also advise on innova car on goa road with the range of prices on road.

The car will be used only sparingly once in two to three months period of time for a month. Your advise on keeping the car in good running condition, will be of much help.

Thanks.
