few years back my BAXR6 had bad smells coming from a/c vents,im not sure if ya can still get em but i bought a COMA auto air fresh bomb(similar to flea bomb for ya house)all windows up,engine running,a/c fan on high,a/c fan on recycle,front seats forward,placed bomb in rear passangers footwell and let it rip.10-15mins later the bomb finished,nice clean fragerance and no start up smell anymore.the only problem is if ya fussy like me ya have to clean ya interior afterwards.but a least the smell had gone. :) p.s the GLEN20 sounds like a good idea to.
