I really like the Manhatten PM and am considering purchasing it as my very first LV. But at over $1000 I want a quality bag I will still want to carry 10 years from now. The Speedys are still around, and in fact they seem to be all over. I like the Multi-Color bags but wonder if women will still be using them 10 or 20 years from now (partly because they're white). Should I go with the known classic or take a chance with the Manhatten?
