Q. Which is better Honda Amaze base variant, Elite I2O ERA petrol,Wagon R, Grand i10 and Tiago XZ Plus within 6.2 lakh?

Wagon R is a matchbox I think personally. Tiago is a good looking car but personally I do not like Tata engines. Honda Amaze is a very good car and maybe slightly slightly better than i20. But in terms of look and feel i20 is definitely the best.

No need to count Grand i10 or Wagon R if your budget is above 6 Lakh. My personal suggestion would still be i20 Elite Magna/Sportz.

Elite i20. Go for it.
