M2 are awesome guitars, I had mine since 2002 without a single problem.
Everytime I change strings I check its setup and since 2002 when I did the first setup, it NEVER needed another setup.
So far no rust and no spots without paint.
My prestige from 2009 never left the house but has some rusty screws and some back spots without paint, you can see its wood.
M2 is a guitar to keep close cause it'll never fail on you.
Mine is transparent purple and has a beautiful ash top.
In 2002 a guy on brazilian ebay was about to get married and needed money, I was selling an old marshall JMP1 pre, he offered his brand new M2 to exchange cause it'd be easier to sell my JMP1 than find somebody who wanted that M2 model.
So I exchanged a crap old pre for an awesome guitar and he got married to a fugly chubby japanese girl
Sorry for the crap quality but it was taken around 1994, that's the one with a pink evolution, it has a angled neck hum(hum with the size of a single) which to me gives it a "progressive" looking
