Chevrolet's retail site does advertise a powertrain warranty of five years and 100,000 miles compared to Nissan's five years and 60,000 miles, and the City Express comes with Chevy's Complete Care scheduled maintenance program for two years or 24,000 miles, something Nissan doesn't appear to offer as inclusive.
Update: Chevrolet wrote to remind us that pricing for the 2015 Nissan NV 200 hasn't been revealed. In addition to the longer powertrain warranty and Complete Care maintenance package, Chevrolet confirmed the City Express "does offer more features, including six standard cargo tie downs, optional left and right side door glass and a second rear dome light in the cargo area and a different transmission that the current Nissan NV200." Also, the Bowtie version "will offer more build combinations - this is an important factor for many of our customers."
thats what i like about this, although they share a lot of similarities, since they are from two different brands you can expect all the details to be different, one of them being the warranty offered,
