We've had it for 2-3 months now and its only got 600k's on it - my dad is still driving his previous car so this one has just been sitting in the garage unless i'm driving it.
I'm not sure if it'll develop after time but there's no reason to think that it would. I've been listening for the note when i read this thread a few weeks ago but i still can't pick it up no matter what i try.
