Be SURE they have not been "punched", marked on BMWNA's books as sold. This is very common with units such as these. If so the warranty clock started the day they were punched and they no longer have the full 48 months of warranty.
SA is nothing to worry about. SULEV has slightly lower hp, but if you're satisfied with the performance that's nothing to worry about either.
