Hello, I am interested in your car, but the price seems a bit high. Is there room for negotiation?
It is a great car but I am open to a reasonable offer. 
I am just looking at the blue book value, and it priced fairly high. I would be willing to offer you $2,500
I'm afraid I cannot go that low. It is in excellent condition, clean inside out and is a very reliable car. Lowest I can go is $4000.
