Washer/dryer co-op question

When I purchased my current co-op unit, I was told no washer/dryers could be installed although it is not expressly mentioned in the (extremely old) house rules. I always get the current sales mailer cards from real estate agents in my mail and I like to look them up online and see what ideas people have had for renovations etc. Today I found something VERY unexpected though. A larger unit with relatively new washer/dryer installed. So, i'm annoyed/optimistic/confused/jealous/hopeful. I have never seen this before from checking out units in my building though and most are nowhere near the size of this one. So my question...is knowing this any kind of indication that they will more likely allow washer/dryers now? Is knowing about this other unit and/or the other unit existing something I can use to my benefit when submitting plans to include a washer/dryer? Or was the other unit more likely just a seldom exception because of the large size and needing to attract wealthier owners (can they do that?). [less]
