Starting in 1993 all 850's also got a passenger side airbag, which is not a big deal if you are the driver, only the passenger! Also R134a CFC free AC, ASC+T is standard, (I think the +T was optional in 91 and 92), air pump for lumbar support on the driver side, chrome interior door handles, and maybe a few other very minor items. However starting in 1996 the engine is larger and the transmission is a steptronic 5 speed automatic and electronics are OBDII compliant. Check the archives for more info
