It's definitely true. Honestly, if you're selling, I'd highly recommend it-Ritchie Bros. does an incredible job with their refurbishment services.
They can take a machine that's seen some rough days and make it look professional and auction-ready again. Between the deep steam cleaning, professional paint touch-ups, and interior detailing, it really helps drive up the resale value. It's one of the best ways to make sure you're getting the most money back for your equipment.
