What would you do with this one?

Hello, I have recently bought this bike and now I’m deciding how to rebuild it. Or if I even should do it. The thing is that this bike is in original condition and runs perfect. Even the shifting works like a charm. It runs 3x7 200gs. I am definitely buying new (wider) tires, some different bars as well and will do complete polish, new chain etc. But I am open to your suggestions. Any ideas? Cheers, Lukas
