This model came with dual-tone colors inside, often using beige and black. The dashboard had a simple design with a basic music system and knobs for climate control.

The Isuzu MU 7 was a massive vehicle sold in the Indian market. It measured 4,955 mm in length and 1,805 mm in height. This car had a broad body that looked like a large van from the side. At the front, the car had a simple chrome grille and big headlamps. The design was based on a pickup truck. It came with 16-inch alloy wheels and side steps to help people climb inside. This model was available in 3 main colors including white, silver, and black. There were roof rails on the top to make it look even taller. The back of the car was flat and had a large glass area.

The Isuzu MU 7 faced very strong competition from big brands in the Indian market. Its main rival was the Toyota Fortuner, which was the leader in this segment. Another major competitor was the Ford Endeavour. This model also had to fight against the Mitsubishi Pajero Sport and the SsangYong Rexton. The price of the manual version was 20.58 lakh rupees. At this price, the car struggled because rivals offered more options. For example, the Toyota Fortuner had a better automatic gearbox than the 4-speed unit found in this model. Most other SUVs in this class offered 4x4 systems, while the car mostly came with 4x2 drive. Buyers often preferred the Ford Endeavour for its better interior. Many people chose these other cars because they were more popular across India. This made it hard for the Isuzu MU 7 to find many buyers.
