They need to be refurbished an I'm looking at selling one staggered set once done. My question is though, what is a set of refurbished Borbet B worth in 16x7.5 (et20) & 16x9 (et15) sizes and 4x100. The refurb will be back to original, silver painted, diamond cut spoke faces and either diamond cut (original) polished lips. I'm trying to weigh up if its feasible for me to get them refurbed or if I should hold out for a staggered set. They are a rare wheel and its very hard to find any recent threads or for sale adverts to give an indication of their value or what they have been selling for.
