I'm concerned about the amt auto box, is amt any good

We had a Suzuki Ignis with an AMT for three and a bit years up to last Oct. Based on that, the answer to your question is, no, not really!.

If just tootling about town at a relaxed pace, they are not too bad. If out on the open roads at a reasonable speed and taking manual control of the gear changes, again, not too bad. But in most other situations, including multi-storey car parks, they aren't great.

My Mother in law has an i10 Premium SE auto, but this was a late previous shape with the t/c auto. It would probably be slower and definitely less efficient than the new model, but all in all a much more pleasant thing to drive.

CVT is all well and good (and I am a fan as we had a Jazz CVT for three years before the Ignis, it was excellent!), but if you set aside (full) hybrids (as opposed to mild, MHEV), there aren't that many small cars use them. Post facelift (2020 on) Suzuki Ignis and Swift (including new model) use them, current shape Dacia Sandero and Sandero Stepway also use them but I'm struggling to think of any others.
