In standard configuration, the 991 interior is a bit "busy" IMHO. Lots of metal stuff in a space far smaller than a Panamera which can absorb the busyness better. If you are looking for a calmer and more restful interior, talk to the Exclusive folks at Porsche. The expresso interior on the platinum 991in the Exclusive salon at Frankfurt was beautiful, while the more basic grey interior on the blue car was irritating to me. Each to his own, but if restful interiors are important to you, sit in some different configurations before placing your order...
