Sprinter bodywork in Poland

Hi, I’m going to buy a sprinter that’s close by, but there’s some bodywork to do on this one, because it’s extreme, the emphasis is on extremely rusty. He gets new doors from me, but the B-pillar is strongly corroded, the Dif rear axle, leaf springs, brakes, and and so on. It’s also very important: even the sleepers have collapsed. That’s why I thought I’d bring him to Poland for the bodywork. r Workshop made very good experiences? Are the costs for bodywork directly at Mercedes in Poland significantly cheaper than here in Germany at Mercedes? Have asked the question already in a different area, but come here now, because I was out of place in the purchase consultation.
