Tata s still lagging in most features

Actually I bought a 2015 model bolt xt diesel top end model as new from Concorde motors Chennai as they offered me some discount in price.. I m facing fault in harman music player touch s not working precisely.. Gear shifting s worse.. Stepney s not alloy they have given normal wheel and it s mismatching in radius.. Performance s good.. Interiors are much better than the old tata vehicles.. Exterior can be improved.. Steering s too small to handle.. Mileage can be improved..
