When evaluating a buggy, prioritize the engine displacement (CC) and cooling system (water-cooled is preferred for high-intensity use). Ensure the chassis is made of high-strength reinforced steel with a powder-coated finish to prevent corrosion. For performance, verify the suspension type, such as independent double A-arm suspension with adjustable oil shocks, which ensures stability on uneven terrain. Additionally, check the braking system, specifically four-wheel hydraulic disc brakes, for maximum safety.
