My biggest regret was allowing my Mum to convince me I was too old for my ponies and should sell my whole collection when I was about 12/13. I had well over 100 ponies (all 80's and early 90's ponies), the fan club carry case, castle, nursery, salon, ballet school and a couple of other playsets that  I can't quite remember. All in great condition too, I never cut the hair or drew on them or anything. I wish I could have my collection back, but it's all gone :-( I've managed to get a few G1 ponies back, but they're normally in horrible condition. But I kind of like 'rescuing' them :-)
