Umm 4x4 Entrepreneur – Portuguese off-roader from Alter do Chão as a commercial variant: four-cylinder engines, 1,632 to 1,700 kg kerb weight, 2,600 kg gross weight, width 1,580 to 1,660 mm
UMM (União Metalo-Mecânica) was a Portuguese off-road vehicle manufacturer based in Alter do Chão. The name Entrepreneur, French for businessman, denotes the commercial variant within the 4x4 range, with a pickup bed or box body instead of the closed off-roader bodywork; the varying spellings in the model names stem from inconsistent data entry in the registration records.

The register lists 6 versions with four-cylinder engines, kerb weights of 1,632 to 1,700 kg, a consistent 2,600 kg gross vehicle weight and widths of 1,580 to 1,660 mm.
With its rugged off-roaders, UMM mainly supplied agricultural, forestry and public-sector-adjacent users in Portugal as well as export markets in Africa; the simple, repair-friendly engineering with a ladder frame and leaf-sprung axles was designed for hard daily use on poor roads. Against the far higher-volume competitors Land Rover and Toyota, the brand remained a niche player before vehicle production ended.
When buying used, check for rust on the ladder-frame body and bolt-on panels, the condition of the transfer case and axles on four-wheel-drive models, and the clutch, plus the leaf springs and shock absorbers, which are often worn given the tough duty cycle of these vehicles; parts availability is limited since vehicle production has ended, so common wear parts from related vehicles of the era are often the most practical solution.
