WTB- 1968 Barracuda Fastback

If this was a 67 or 69 I say 11,000 to 14,000
So because it’s a 68 it’s valued a bit more due to rarity so between 15-18 if it were clean with no issues but also because it has the interior and dent issues, would you guys say 12-14 would be a good assessment? I’m just trying to see where I should cap out before I’m overpaying. Also keep in mind it’s a 318 car
