i have brought one brand new 3 months ago. so i dont have any idea about maintenance. but i can assure that it has very good fuel consumption over the other nissan cars. it does 13 km/l on my trip from Ambilipitiya to Kandy and back to Ambilipitiya, 400 km. it does 16-17 km/l on roads without any traffic. its a very comfortable and spacious vehicle. very good choice for ur money.
