Are you aiming for a brand new look and feel or a sympathetic refurb...or maybe somewhere in the middle?
An MC21 found me in October last year and I decided to go for a "deep clean" over winter, whilst refreshing parts that need it to MOT & run safely. I want it to look period for this year, run it around a bit and then decide what to do next winter. Maybe spend the big bucks then (yet it's still cost a bob or two to get to where I am now!)
