You mentioned three cars out of which two are SUVs and Innova is a MUV. Force One is costlier and gives lesser value for money than the other two, again Force Motors' brand value is lower than Mahindra and Toyota and Force also lacks in service center network. Coming to Scorpio and Innova, we will suggest you to go for Innova as it's the ultimate family car and very comfortable.
