You can build a car interior that pretty much lasts forever, but it’s not cheap. There’s plenty of 60s and 70s Mercedes around with MBtex and zebra wood interiors that still look pretty much new after 6 decades of regular use. It’s eerie how good those old Mercedes interiors are, I’ve seen cars in the junkyard that were almost completely crumbled to rust powder, but the interior still was flawless. A good upholstery shop can also rebuild a car interior.
