I bought Xeta GLS 4 months back, car looks great when compared to the price of its same class vehicles. I read most of the reviews in Mouthshut and wondered how every ones review matches. On an average im getting 12-14 kmpl within city drive. Xeta is very spacious when compared to the Santro(Which I drove previously). But if you are concerned about the finishing, then this is not the right choice. Xeta has to be improved a lot on the finishing work and cheap plastics.
Another major issue is the beam(i.e. frame) which is in front of the driver seat. When you turn right, the beam obstructs the fore coming vehicle, which I never faced in other vehicle. Tata should concentrate on the design of the beam
Whatever you have it over the dashboard gets reflected in the front glass(if you have shiny package stuff, the impact is more), so will not get clear view of the road. Either the positioning or the type/quality of the glass has to be altered
