Best car under 6 lack

It's such a best sedan type car in low price compare to other sedan type car . Most stylist look and bset performance. They said it's give milage 19km/l but it just gives 13km/l , it's disappointed think. There is lots of boot space provided. No rear speakers provide when you reached speed 95km/h back seaters can't hear music. Gear set up is such difficult campers other car.
