more rare than the sedans.. but not as rare as the 5 speeds..
the swap to 5 speed s easy though... the autos have a stronger built tranny than normal legacys.. but with only 165 HP you can go with just about any legacy AWD tranny temporarily if anything happens.. or swap in ant 5 speed from a 2.5RS or a legacy (long as its AWD) and your set.. parts are cheap too... most of the main parts are the same fro the non turbo legacys.. of which there were alot of..
legacycentral.org has alot of good info.
