I have a 1992 Nissan 240 SX SE convertible with a tan leather interior that is in pretty good condition for being 16 years old. The back seat is actually what I consider to be in great condition- no cracks, rips, or marks. The front seats however are in fair condition. The leather is very worn, many cracks. Not too many marks though. The driver's seat however, has two small rips on the actual seat portion. I love having the leather, but with the wear and tear it isn't as luxry adding as it should be. I don't know if I should leave as is, being able to claim I have leather, or redo the interior. To re-upolster in more leather at this time would probably be out of my price range and I would have to do cloth. Would brand new cloth seats increase the value? It might look better, but it isn't leather so I am unsure.
