1078 total Cobras were made. So, even though the car market and collector car market is much bigger nowadays, don't hold your breath for a million bucks for your SyTy.
Still, a good idea to:
- avoid mods that can't be reversed (even a thoughtfully modded truck, while worth more NOW, will be worth less later).
- Keep those original parts!
- maintain, restore, and maintain some more.
