hi I am interested in your Nissan 
You've got great taste in cars. This was my baby but it needs a new owner and I would love to sell it to you. Got any questions for me?
Why are you selling her, does she need any repairs?
She just doesn't suit my needs anymore - My family has grown by 2 so we need something reasonable and practical. No repairs needed at all. I've taken GREAT care of her!!
She is a beauty I can give you 5600 for her.
Yes she is which is why I know her value and 5600 is way too low for her. I can knock off  500 and sell her to you for 8K
The most I can pay is 7k
I'm sorry but 7k is too low. Make it 7500 and you have a deal. Its quite a steal at 7500.
Ok I will give you 7500
Deal. Nice doing business with you
