Superb mileage, spacious and peppy engine

Hi guys. I brought sunny in2014. They say the first impression is the last impression if that is true then the Nissan Sunny makes a great one. When I saw the amazing Nissan Sunny the very first time, I instantly took a decision to buy the one as soon as possible. Started with an average mileage of 18 to 20 kmpl. But now after long drives of 150 to 400 km at a stretch and crossing 90,000 km, this beauty has started giving 29 kmpl over highways and 23 kmpl through city and highways and 16 to 18 kmpl in traffic choking cities.The problem I feel is gear shifting is hard in 1st & 2nd .Music system is quality is very poor. Overall a car that gives you adequate power, best mileage, better comfort (though body roll is there on hairpin curves) with safety not at all compromised.
