The Renault Lodgy is clearly the bigger of the two and would offer you more space and comfort, however bear in mind that maintaining a used Renault Lodgy is going to be more difficult than the Maruti Suzuki Eeco as parts availability is an issue even with official Renault dealers, further given that the Lodgy never sold in large number finding parts in the aftermarket will be difficult too. Thus, it is best to avoid it unless you are very certain of the condition of the car and the availability of parts and service in your area.
