GMC Lkw bis 3,5 t (class N1) – registration collective page of light GMC commercial vehicles Sierra, Silverado, Savana and Rally: six- and eight-cylinder from 3,900 to 7,500 cm³, gross weights around 3.5 tonnes
This page is a registration collective page rather than a single GMC range: class N1 denotes, in the European vehicle register, light commercial vehicles with a gross vehicle weight of up to 3.5 tonnes. Gathered here are GMC models that reach this limit, from the Sierra and Silverado pickups to the large Savana and Rally vans and older C/K models. GMC (General Motors Truck Company) is General Motors' commercial-vehicle brand, sharing platforms and technology largely with sister marque Chevrolet but marketed with its own trim and dealer network.

The register lists 34 versions here from six- to eight-cylinder engines of 3,900 to 7,500 cm³, kerb weights of 2,050 to 3,380 kg and gross vehicle weights of 3,490 to 3,500 kg, confirming the classification into class N1 at its upper limit. Lengths range from 5,520 to 7,640 mm with widths of 1,950 to 2,480 mm.
GMC pickups and vans compete in North America with the practically identical Chevrolet models as well as with Ford and Ram in the large light-commercial segment, and in Europe are used mainly as imported and enthusiast vehicles. Gross weights just under 3.5 tonnes allow use with an ordinary car driving licence in many European countries.
On imported GMC models, key checks include frame corrosion, the condition of the leaf springs and the often large-displacement V8 engines, as well as the automatic transmission and brake system to US standards. On the Savana and Rally vans, the condition of the sliding doors and body seals should also be checked. Spare parts are readily available through American import trade thanks to the close technical kinship with Chevrolet.
