Which used Nissan X-Trail 4x4 should I buy?
When it comes to choosing which engine is best for getting the Nissan X-Trail moving, stick with the 1.6 dCi. While it can feel a bit underpowered with seven on board, it's the most popular unit by far and in manual front-wheel drive form, the most economical. The manual version also tows better than the CVT auto version, in case you wish to lug around a caravan. The 1.7 diesel didn't arrive until later in this car's life and so there are fewer available used.
