The SL is the one to go for if you’re looking for an agreeable and capable passenger van that can comfortably transport 12 people on a daily basis. The extra power afforded by the 5.6-liter V8 engine goes a long way in making the NV a truly comfortable people mover and allows it to happily cruise along the freeway without having to worry about overtaking capability. The SL not only goes better, but it's a more delightful place to sit in thanks to standard leather seats, dual-zone climate control, and standard navigation.
