Considering the advanced state of automotive engineering these days, there is a solid argument to be made that there are no bad cars anymore. Indeed, the automotive world has weeded out most of the truly lousy performers. But that doesn't mean that there aren't any current models that would be pretty bad choices, given the clear superiority of other options. Which brings us to the Nissan Sentra.
The Sentra looks good on paper, but it ultimately fails to live up to expectations. Competing with compact sedan stalwarts such as the Honda Civic, Mazda3, and Toyota Corolla, the Nissan simply doesn't shine. Overall, the Sentra is underwhelming to drive and feels cheap--problematic in a class that is growing ever more refined.
Look at a spec sheet and the Sentra has some advantages. Probably its best quality is that it has a roomy rear seat, one that would shame some midsized sedans costing $10,000 more.
