Q. Which is best under 3 lacks among Alto 800, Eon, KWID and Go

All cars are equally good cars .each car has their own strong points and best features one over the other .you have to be very clear on usage and purpose and location of town or city . You may choose accordingly . Kwid and Redigo are trend setters. Alto and Eon are tried, tested and proven..backed by wide service network ..Hence choose accordingly.

To be exact, none of the cars you listed would come under >3Lakh mark. Eon is gone already, Go please let it go. So the competition is with KWID and Alto. Choose Alto in case you need a trusted engine with better mileage + less maintenance. Choose KWID in case you need value for money (big Car, Boot, Ground Clearance, infotainment).

What would be your concern of features then kwid if safety then alto 800 as both eon and kwid are 0 star rated in safety while alto 800 has 1 at 100kph crashkwid has 0 eon 1 and alto 800 2.5 at 80kph
