Q. How spacious it is, is it compatible for 6 seater with driver - Grand i10?

No . It’s not meant for 6 ppl . It’s a five seater compact car , if the passengers are bit bulky and heavy in body posture , it may suit for 4 ppl . You cannot have a more storage room at the trunk . Basically it’s five seater car .

Its a family car...as per indian scenario you can set 5 people in car(including driver). if you want 6 seater car then please check other big cars like SUVs,MUVs like Ertiga, Marrazo, etc.

If u need bigger car with bigger trunk room , go for Creta or Jeep . Creta will less cheaper than the Jeep Compass . U can have 5 seater including driver and comfortable ride .
