Scenic III which engine? and which radio?

(1) I’m thinking of getting me a Scenic III. There are obviously many in this forum who drive a diesel or the TCe 130. No one speaks of the 1.6 16V 110. Why? Is that so bad? What criteria should be applied (if you don’t want to be a race driver) to the choice of the engine? (2) And I noticed something else: If I use the car configurator, there seem to be three radio versions: Radio 4x15W CD MP3 Radio 4x15W CD MP3 Bluetooth Radio CD MP3 3 3D Sound by Arkamys Bluetooth Plug&Music Is the second only like the first, only with BT? And what can the third great, if it is offered apparently only from Dynamique with 500 Euro extra charge to the “base radio”? (3) And another question: I still have almost brand new winter tyres of my current vehicle in the format 205/55 R 16. Could I continue to use the, with corresponding rim, at the Scenic (dumb question probably, but I really don’t know about it so much). Thank you for your tips and hints!
