Have you ever turned down an offer for you car that was too good to refuse?

I would say no because if it was too good to refuse I would have taken it. every car i have had and currently own are always for sale

I guess I would define too good to refuse as "more money that it cost me to complete this entire project" (which is substantial). And yet, I am still torn because I am attached to this car now, even with zero history with this specific car.
