I would certainly call and see what they say. Keep in mind, they would most likely pay "market value" not BJ crazy money.
I've had many people offer to buy our LeMans as it had 54k on it when we bought it and is in incredible condition (8.5 out of 10). However, I love the car and could not see selling it. However, if you are wanting to make heavy mods (more than bolt on) I would definately put your feelers out for a buyer...
