Congratulations SpringMummy - how wonderful.
After I had my DD at 41, a gynae/obstetrician my Mum knows was very surprised to hear that I did not have an ELCS authomatically given my age. As I understood it, the reason was that after 40 (or perhaps younger) your pelvis starts to seize or fuse or something and if you haven't already had children to stretch it (or something) a VB is going to be harder.
My consultant (who was fab in every other way) never suggested anything like that to me.
I ended up with an EMCS after induction/epidural/attempted forceps, so I suppose my view now is that it would have been a lot easier to have gone for an ELCS in the first place. However, had someone put that argument to me before the birth I might well have wanted to try a VB anyway to avoid the potentially lengthy recovery period (and I suppose to see if I could manage it).
I still have no idea whether my elderly pelvis contributed to my EMCS or if it was just bad luck.
What I would say is that comparing the experiences of people I have talked to since who had VBs, I am not sure I had the worse bargain, at least long term, in that my pelvic floor is in reasonably decent condition now. The problems I did have post-birth (sleepy and then dehydrated baby/me re-hospitalised with chest infection etc) probably had more to do with the emergency nature of the CS and the GA rather than the CS itself. So I suppose, if your consultant thinks that, being older, you have a high chance of needing a CS in the end anyway, it might be better to opt for an ELCS straight off.
