My car was deemed a total loss, and are going to make me an offer, I checked the kelly blue book value. It showed the suggested retail price, trade in price, and a private sale price. Which will they take into consideration?

They look at the condition of your car and what similar cars sold for in your area. If dealer prices are involved, they compensate for dealer overhead when making as actual cash value evaluation of your car. If you can find similar, and I mean really similar cars, selling for more in your area, they may take that into account also. There may be some "fudge factor" if they are also paying for you to rent a vehicle while yours is inoperable.
