I just tested zeta glx yesterday...oooh my god its just super...also the ac powerful compared to old versions...millage I dont think we will get good...spoiler is a common feature also lot of innovative stuff...if u got 3L budget pls go for zeta...alto should never be compared with this...the first versions had ECU chip complains but now it is fixed...but resale value has to be noted ...tata is bad for very long termers...
red , green are very good but all tata vechiles have a problem they use very very low quality paint...so after 3 to 4 years car looks very old...but it seems zeta is improved a little bit...in my opinion go for zeta..its value for money...
Zeta is the Best
