well im looking at buying a ba/bf falcon xr6 manual and would like to know what things i should look out for what problems do thay have.

not much barnzey, they're a pretty good package for what you pay. Differences b/w BA & BF you can find on the net. Apart from the obvious checks get a RACQ report done if your not car experienced. RACQ nitpick everything but the check is thorough. Good luck
