Hi guys, I'm new to the forum so be gentle with me.

I'm in the UK so answers relevant to this country's models please.
I'm close to buying a 2023 Jazz EX. I want the facelift version but there seems to be very few of them about from that year or people aren't selling them. I notice that there's an Advance (not Advance Sport) trim which appears to be similar other than having nicer wheels so it seems odd that they sat alongside each other in the range.
* Am I right in thinking that they are very much alike but were on sale simultaneously and was the Advance actually a replacement for EX? Are there any other differences? Should I chose one over the other?
* Were there many EX facelifts made in 2023 and would they all be 73 reg? I'm struggling to find one within 50 miles of where I live (edit: Bristol area and yes, I'm keeping an eye on Waylands).
* I looked at a pre-facelift EX recently and felt a vibration in the lumbar area when the engine was running. Is that normal? It was rather high mileage, wasn't very well looked after and appeared to have been a lease car so it might have just been that one.
* I gather Android Auto can now have two apps side by side? I'd like to have Google Maps and Musicolet running together, is that possible? If so, I might drop down to SR trim and get a reversing camera installed as that's the only really useful difference other than the heated seats and steering wheel. Good move?
* Most of our mileage is around town and short runs on dual carriageways, can Adaptive Cruise Control and Lane Keep Assist handle roundabouts and is the Jazz OK for long motorway runs? (Comfortable, no engine drone, ACC and LKA lets it more or less drive itself, etc.)
* Finally, why the boring colours? Red is the only interesting option but as beautiful as it is, it can attract more attention from our friends in blue, not that I speed much these days with all the cameras everywhere. I noticed in the poll that more of you have red cars than the other colours so I guess it's not a problem.
Thank you for your thoughts, I'm sure they'll be very useful.
Simon.
