Most of us don't get another chance at one that we let slip away before.
My suggestion is to make a reasonable offer remembering that the seller is in charge. Don't try to low-ball him and pi$$ him off.
It sounds like a good solid car with the right options.
If he doesn't budge on his price then you have a decision to make.
When I bought my '69 I felt that it was over priced a little but it was too good to pass up. Never regretted buying it.
Good luck.
