Agreed there is no logical approach if you simply have "new car-itis". The cheapest solution is almost always to fix it.

But if you're thinking you have a lottery ticket with the red interior I would think twice. It won't add any value to a trade-in, and minimal value to a retail sale. There has been a full Imola interior listed on eBay for years now at 2900 and hasn't sold. E53's are not valued at a high enough dollar amount for owners to justify spending that kind of money on a fancy color interior. I would anticipate finding a buyer in the 1500$ range. Freight shipment on a pallet will cost around $300 minimum. FYI I am not interested as a buyer, I own a BMW dismantling company and know the market. Good luck with whichever way you go.
