Tata Vista is a great car to drive but only when purchased new. The car comes with a 1405cc, 4-cylinder diesel motor producing 70 BHP and 135 NM of torque. The torque generated by the engine is very low when compared to the others in class. The engine brings good mileage and decent driving experience but comes with various problem after a period of time. It starts making more noise and also emits more smoke than the desired value. Even if it has been driven with care, the engine requires a lot of care. You can first get it checked thoroughly from a mechanic before buying as the factor which facilitate the deal is its price. If there is no major fault, you should definitely go for the car and drive it for another 30,000 km easily.
