1968 vs 1969, 1970 dart values

Thanks for the response. This is my problem-
1968 is my favorite, by far. I’ve found the right color, engine, transmission, and condition. It’s everything I want. I would guess it’s a high number 2 car. They are asking quite a bit above number 1 condition, according to Hagerty, which it typical on the internet. I’m sure there is wiggle room, but I don’t want to insult them by bringing up Hagerty’s numbers. I’m not buying for investment, and I don’t mind paying a premium for the right car.
Then do it. As long as you won't kick yourself in the future for paying too much. I paid more than I should have for my 70 Swinger but when I sell it the loss will just be the cost of having years of fun and enjoyment. That can and does come at a price.
