I started a very small company several years ago making garage refrigerators called Tough Stuff Appliances that I have since sold, but it might give you guys a few simple ideas to make your old fridge stand out. I would strip the fridges down, sand, tape, mask and paint them with hi quality automotive paint. Starting out I was using rustoleum red out of a can and shot it with my LPHV gun and it was just as nice as using the pricey automotive paint. I then added aluminum tread plate on the doors. Here are a few pictures of what can be done to mini fridges and larger fridges to make them stand out.
Sadly the guy who purchased the business from me went out of business.
