The difference between a nice interior and a fantastic interior is in the details. It always come down to nitty-gritty things IMO. The biggest clue for me is hardware. If hardware is well done, then you can be sure everything else is of high quality. One of the nicest hardware manufacturer is Nanz company. They can customize each knob, each handle, and each pull. The possibility is endless. The result, of course, is timeless.
