The design of the Mahindra Bolero has evolved over the years, with several changes made to the exterior of the vehicle. In its earlier iterations, the Bolero had a more angular and boxy design, with sharp lines and flat surfaces. However, in more recent models, the Bolero has taken on a more rounded and streamlined look, with softer curves and more aerodynamic styling. Other changes to the exterior of the Bolero have included updates to the vehicle's front grille and headlight design, as well as the introduction of new exterior colors and finishes. However, despite these changes, the Bolero has maintained its distinctive and utilitarian design language, which is well-suited for off-road driving.
