Except for limousines, I don't know any other cars that can hold seven passengers. You should try SUVs or vans. SUV's and vans can hold a large number of passengers comfortably and still have space for luggages. They are cheap, safe, and comfortable to ride in. Some good SUVs are the Isuzu Crosswind-not available in all countries, Revo, Innova, they can hold 7 persons and can give good mileage. Some good vans are Toyota Hi Ace, Nissan Urvan or the MB1000. They can hold pretty much the same number of passengers and luggage, the only difference are the features you could get from them.
