I'm more of a mid-range than luxury bag buyer but always had it in my mind that a Chanel flap was like the "ultimate". Looked at a pristine vintage Chanel flap in Fenwick a couple of weeks ago at £7995, had a good look inside and out, and it was lovely but also....just a bag. I don't think I'd ever justify it even though I could save and buy one if I wanted to, my first, second and third cars all cost less than that (I am 40 though!).
I think I'm just happy at mid-range and would rather spend the money on our property or travel expenses - but totally get buying one if you are financially able to do all of the above and it not make a dent.
