Overall, It was a good experience with my Nissan Sunny that I bought in July 2012 and used for 10 years. It ran over 1.45 lakh without any major issues excluding the clutch failure once when I was on a road trip with my family.
Pros-
1) Nice after-sales experience.
2) More comfort as compared to Honda City and Maruti Ciaz.
3) Big boot space.
4) Amazing engine performance (diesel)
5) Built quality seemed to be better than other sedans in the same price bracket.
Cons-
1) Servicing is a bit expensive.
2) Exterior design could be better.
3) Clutch is on the harder side.
4) Less availability of Nissan service centres.
5) Light throw wasn't the best, can be difficult to drive at night.
