My 2004 Maxima has tired looking front seats. There are no rips nor tears, but the finish on the seats is rubbed and has lines in it. I read that Maximas/Infinitis have a variety of power seat configurations, so I'm hoping to avoid the sand trap of power seat troubleshooting. There seems to be an abundance well preserved seats up North. Do I try to restore the existing seat surface? Do I look for replacement seats? What's the smart solution? Is replacing seat cushions while keeping the seat frame an ordeal?

It's interesting that while Southern cars are often rust-free, the interior gets cooked. I noticed that it's common to see Northern rust buckets with excellent interiors. Would Nothern salvage yards be a good place to look for better seats?
