Though some
rivals do offer a more spacious back row, head and leg room is fairly good on the GMC Sierra 2500 (especially on the large «Crew
Cab»
models, which we particularly recommend to buyers who'll need the back seats to comfortably accommodate adults on longer journeys).
Progress is lively, if not quite as effortless as in the most powerful versions of some
rivals but, surprisingly, there's more noise and vibration in the
cab than with the single turbo dCi 115
model.
