The only thing that I am hankering after right now is a Zaskar to base a 700c drop bar road conversion too in another iconic motorsport livery... maybe not even a retro one but a late one with discs to make the brake conversion easier. It would take a longer fork too, which would also help (I'd prefer an older one tho)
Like Stevo says, an early Palisades Trail would get me going too, but only beacasue it was my first proper mtb after my mint green Raleigh Montage.... but I can easily live without one
