I think Epi is pretty forgiving where scuffs and minor damage are concerned. You can get those areas tended to by a bag spa or leather crafter. I can't say if creases will eventually come out but if the leather is still supple, you could stuff it with clothes etc to fill her up and see if the creases relax over time. I saw a great looking green speedy on our local ebay and it was tempting... I guess you just have to make sure the inside is still nice and intact and no major damage. Just ask for as many photos as possible.
Ah thanks so much for the guidance! Would appreciate the listing on ebay if you have it available! I was also looking there too. Have been eyeing some on fashionphile too. I've been noticing issues like dents on the bottom of the bag, wearing of handles, and scratches, but it's also a bag that's from the early 90s so hard to discern what is more or less "forgivable" with regards to wear.
