Poor perfomence

Cheap quality of plastic, goodcomfort, bad Fuel Economy and Gearbox. I brought a new grande on june 2011, at vijay sales corp.vellore(T.N).

Exterior looking bad paint quality no value for money, my car paint is dew white lot of black shades in the side body, eletrical work not good, low engine pickup, heavy noise inside the cabin,power window not working,combi switch not working since I purchase the car. I complaint so many times but no response at custumer service very bad service never seen before at vijay sales corp.vellore.(t.n) dont buy any tata vehicle at this show room no custumer service no spares avalible they are cheating the custumer they only showing interest to sell the vehicle very very poor service.Want to improve the quality of dash board plastic, outer looking very huge size, engine noise very high, I feel like sumo victa engine noise, mahendra xylo is better vehicle to compare this sumo grande. Low fuel economy AC is better cooling I like more before buying this vehicle  but I feel very bad after get this sumogrande. Dont buy this vehicle.
