No one should ever buy a car based on another persons opinion and without a studied/informed choice. Every car is different in quite a few respects . Your friend will never be able to test drive a car for 5-6 hours to judge whether there will be back pain etc and fatigue is a composite of several factors, and not the seat itself. Fiat cars are amongst the most driver oriented in terms of overall feel, south of 15 lacs. Any other car with loose steering , while great in city, will be a PITA on long highway journeys, since you have to continuously adjust. A heavy, weighted steering at high speeds goes a long way in alleviating fatigue of such nature.
