For the New Drivers or the Sunday driver, Nissan March can be used easily in urban, for look to parkin', fuel, this car is great..
Chinese Companies, such as Sinopec, their sources of fuel are the same as other companies, they took the fuel from Singapore's Fuel Market, they supply the China Product just inside China, So don't worry
Maitance question, In a lot of people's opinion, go back to Manu's factory got better quality, Factory parts..etc...But outside may give you other sorts of parts, so
Choice is yours..
