I think TATA is new in game ,it will take time to work out all issues , same for Mahindra , in Korea or japan or Europe carmakers have a huge skilled workforce with tons of experience and most carmakers are too old in market ,so they are quite well established and their products are refined , TATA Mahindra make safe cars now ,but comfort and features and tuning the engine is somewhat a bit lackingTata has cracked that segment - both Nexon and Punch are excellent buys in that segment. But lots of niggles in the Harrier and Safari. Obviously, most get hassle free cars but as a ratio a significant amount get cars with issues. India needs a lemon law.
Can't go wrong with Suzuki, Hyundai, Toyota and Honda - from customer service to availability of parts, they are always prompt. The Europeans launch good products but their A.S.S is pathetic - most notorious is Skoda.
