Front passenger seat - reversible?

Hi all,

im thinking of getting an ah30 that i will slowly and ultimately convert to a camper. 
 

I like that on the 3 series there is a long slide on the near side, i.e. a single rail for front two seats to slide to any position. Anyone know if this was only an option or standard on certain trim levels?

also, can the front passenger seat be reversed to face backwards (not on a swivel)? This would be useful for solo camping. May as well also ask - if it can be done, is it legal for a passenger to sit in the backwards facing position whilst driving?

Images show some seats have integrated seatbelts, some don’t. 
 

thank you!
