2 months usage review

Hello friends, I bought my Renault Kwid 2 months back on Nov 14th. Gone for two long rides of 400 kms each. The comfort during long drive was appreciable. The Steering seems  more stable at higher speeds of 120kmph. The mileage was not up to the mark. I am getting around 15kms in city and around 17 on Highways. Expecting the better mileage after first service. No need to explain about exteriors, interiors as many of u were aware about them. But I will tell you few points. The Navigation system is suitable for cities but not at all use full for rural India. The touch was little bit laggy, The call clarity over BT was awesome but the music player over BT is lagging severely. We can find Minute vibrations of Gear Rod. The ground clearance claims to be 180 but even the Indian speed breakers breaks the bottom of the car instead of speed. I hope it might be some designing error. There was some minute errors in designing. If you close the front door when the back door is completely opened it will leave some minute rashes on the back door bottom. The accessories provided by Renault were not up to mark. The bad thing is the dealer is making it mandatory to have a 9 accessories list which costs around 13500. The dealer claimed around 5000 for extended warranty for which there was no intimation from Renault as indicated by the dealer. As many people said, the Engine was noisy. 

Guys comment below for any clarifications. I am here to assist you guys.
