This is hands down the worst car I ever owned. At around 30 thousand kilometers, it started to leak water every time it rained a little bit harder, both passenger and drivers side door rubber/seals. At around 85 thousand kilometers a blown head gasket, astronomical cost to repair, close to $2000. 89 thousand kilometers, check engine light constantly on. I owned several economy class cars before this one and Sentra is hands down the most unreliable car I ever had. I will NEVER own a Nissan again.
It handles fine for an economy car, good on gas.
It's beyond "improvement", Nissan needs to make TOTAL changes when it comes to quality and reliability of their cars.
