In my point of view, A worthy replacement to the Santro, the i10 does everything you expect from a Hyundai. Space is good, engine's trustworthy(both the 1.1 and 1.2) and the ride balanced. Hyundai service quite commendable too.
Bad: The i10 nears its facelift. Lack of a diesel option make a lot of buyers look elsewhere.
Verdict: Hyundai started its journey in India with the Santro and the i10 seems to have taken it forward from where the Santro left, making way for this very car. Hyundai is planning to position the i10 replacement slightly above it, so if you can stretch your budget, it can be a great buy.
