Our old GE Monogram 42 inch built in fridge was still working fine after 25 years (except for the ice dispenser) but we wanted a new stainless steel one.  This one fit perfect, the electrical and water lines and cabinetry all fit perfectly without any modifications.  Took only an hour for the installers to finish the installation.  Works perfectly, is very quiet and we have zero complaints so far.  Not as fancy and sleek as the Monogram but also less expensive.  Hope it lasts another 25 years like the old one.
