Mercedes Benz Sprinter
The Sprinter is all set to take the American van markets by the storm. This year the Sprinter is completely redesigned with new infotainment, engine, and interior styling elements. Even without the changes Sprinter was a great choice. With its above average interior, bigger cargo bay, and a number configurations the Sprinter is a lucrative choice. Though it's still hounded by low powered engine and a higher price tag. NV cargo on the other hand has better acceleration and price.
If you consider value for money than the Sprinter is what you get the deal at.
Ford Transit Cargo
Ford is the master magician when it comes to commercial vehicles and its biggest spell is the Transit Cargo. The Transit's threshold on the Full-fledged vans market is what Nissan or any other brand wishes to achieve. Ford delivers a bigger cargo bay and a high powered engine, plus Ford's reliability is where its true USP lies. Nissan on the other hand, stays just a tad behind in every aspect and compensates it with the price.
The Nissan is a decent van which delivers average specs for everything. If you are running tight on budget then Nissan is a life savior, otherwise Ford is a far better option.
GMC Savana 1500 Cargo
GMC Savana is a strong offering from the house of boxy vans. It has power better than the Nissan NV and a similar cargo bay but GMC is a better option. You know why? Because of its class leading towing capacity. Nissan is nowhere near to the GMC. Other aspects like the acceleration and configuration are similar so the thing boils down to the price.
The GMC Savana's price is competitive to that of the Sprinter and Savana, Nissan compromises price. So if you are low on budget then the Nissan is probably the right van for you. However, if you are in constant need to trailer heavy things the GMC would be the better.
