2010 Nissan Altima 2.5 S 4dr Sedan (2.5L 4cyl CVT)
First sedan I have owned in 25 years of owning vehicles, and we've been very pleased with it after 4+ months and 6,000+ miles. The SL is incredibly smooth, quick and quiet for a 4-banger, though the engine noise does come through upon hard acceleration. Have taken the car on 9+ hour rides serveral times now - no issues with comfort (we did get the SL version with leather seats). We have consistently gotten great mileage 34-36 mpg hwy (@ 65+mph) and 25+mpg City. We do miss sitting up high like in our SUV's, but otherwise it's a great car. Virtually no torque steer, steering is responsive.
Heated seats, large gas tank (20 gallons provides a highway range of 600+ miles on one tank!), sunroof, smart use of center console storage and armrest, large glove box, split folding rear seats.
Lumbar support adjustment for passenger side, "Ski sock" (like some European sedans) to get skis or long items inside the car without having to put a back seat down.
