The Nissan X-Trail is often sold as a 7 seater SUV but there is a great deal of debate about how practical those extra seats actually are. Some owners swear by the flexibility of the option for occasional use, while others say it's too cramped for anyone other than small children. The usefulness will likely be dependent on passenger size, trip duration and how often you need to use all seven seats. And, of course, how much cargo space remains when the third row is deployed. The X-Trail's configuration could be the deciding factor for families on the fence about needing a full size 7 seater or a more compact SUV.
