The Sentra is Nissan's most affordable sedan. Offered at a price aimed directly at first-time buyers,the Nissan Sentra provides a roomy and comfortable interior,responsive handling,peppy performance,excellent fuel economy and a green-friendly Ultra Low Emissions Vehicle (ULEV) rating. Nissan gave the Sentra a major freshening last year and,other than two new exterior colors,the 2005 and 2006 models are virtually identical. Despite the update,the Sentra still looks dated when compared to newer models such as the Honda Civic and Kia Spectra. Then again,when you're buying a car for under $15,000,value should trump style.
