I have purchased zeta plus version 1 month ago and have driven about 3500kms. Zeta plus is worth to buy with hybrid technology giving unbeatable mileage of 26 to 28 including city plus highway drive. Riding experience is good as we buy vehicle foe steady drives and not for racing power is sufficient enough. Road presence is good. Servicing cost is low. Pros are Maruti service, mileage and the biggest pro is hybrid engine of Toyota who are leaders in hybrid technology.
Cons are with that kind of price tag basic features like TPMS, rain sensing vipers , good reverse camera , shifter for cvt and key with boot opener option are lacking. They provide very basic remote key for all cars where as in rivals creta or seltos .they provide lid opening or engine stop or start option.
