Uppababy Vista expert needed please!

[Mississippilessly]

I posted a while ago about choosing a pram and got so much helpful advice. We took ourselves off shopping and we think the Uppababy Vista is the way to go. However I think we will have to go second hand. Is there any difference between the 2017 model (I think that's what is in the shops now) and the 2015 or 2016?
Thank you!

I have the 2015 Vista. AFAIK the 2017 model is a bit narrower and but lighter - which is good but not necessarily worth it if you can get a good second hand one. Obviously the fabrics are also different and it comes with a few extra touches like the handlebar covers but I think the big redesign was for the weight and size.

And you can't get a buggy board without paying £££ for the older model now.
