Electric Driver Seat Broken - Replacement Advice Needed

Hello! I need to replace the driver’s seat in my 2012 Ford Escape because something got caught in it, causing it to go off track.

The repair shop quoted me around $750 to replace the parts. Does that sound reasonable?

I’m not very familiar with car repairs, and that price seems pretty steep to me. Does anyone have any advice or suggestions on how to handle this?

Thanks in advance!
