Best car for local businessman

I am planning to buy. I am driving this car since long and its amazing. Its grey colour is fantastic and a blue line is superb. I don't know about his service Its advantage is its electric vehicle. No use of petrol diesel or gas. Disadvantage is nothing in my way. Tata is a good manufacturer of cars because of its safety, I owned a Nexon Zest, Nano, and Indigo . Zest and Nexon performance is excellent in service cost and fuel economy cost and maintenance cost is in the budget
