Not just better quality materials, better quality in upholstery and actually matching the items they are meant to. PUI are full of seams and stitching in the wrong areas or mismatched and wrong colour inserts, out of shape cuts and map pockets that are simply sewn across and not a pocket at all. They are made to a price, some don't care about the finer or not so fine details or how they looked, they just want better than their current worn out and trashed 40 yr old pieces.
