Open box benchmark Bosch

I posted the other day about a Kitchenaid dishwasher at Costco.

Well, I found a benchmark Bosch at a local appliance store for 1199, looks perfect and hasn’t been installed. We would have to install it ourselves or pay $100- how hard is installation?

I don’t think I can pass it up, but is the Benchmark actually nicer? Or is it just gimmicky stuff like the light at the bottom? Which is admittedly cool.

Nervous about pulling the trigger with no extended warranty, like Costco gives.

Edit: I ran the serial number and it was manufactured in December 2020. Not sure why it’s open box, but appears to be in perfect condition. Will Bosch honor the one year warranty?
