Both of my '94 3 Series cars have a passenger side airbag.

My first E36 has been gone to the Big Wrecking Yard in the sky for over two
years now, but my second one sits in the garage waiting for better weather,
and this one has a build date of July '94, which makes it an Early
Production car. My MPV has not got a passenger side airbag, and it's a '93.

Might I suggest you look for a '96 or later because the OBD II engine
management system is superior to the OBD I. If I was looking to replace any
of my cars, or add to my fleet, I'd be looking almost exclusively at the '96
model years and later. I don't think the difference in price between a
'95-ish car and a '96-ish car is going to be a significant factor.
