The 211G155 is a compound feed (a combination of needle feed and drop feed which means the use of feed dogs to push the fabric through the machine) walking foot (alternating presser feet) industrial machine. As far as I can tell, it does not have reverse. The lack of reverse is annoying, but if you're not sewing for a living, it's not a big deal. It will sew your car interior just fine.
No one lives forever, the trick is creating something that will.
