Hello
Hey, is your car still for sale?
Yes, definitely. And it is a great one. Runs perfectly. CARFAX one owner. No accidents. Bluetooth Media. 
Hmm, that sounds great!  How much do you want for it?
I would like 13,500 for it. But I am willing to negotiate on that but can't come down too much. 
Well, it says on the ad it has 100k miles on it.  It's a nice car but that's quite a bit, honestly.  And it's already 6 years old
That is the dealership maintenance package which is good up to 100,000 miles. The car only has 34,000 miles on it and is a BMW i series.
Oh, I see I need to work on my reading comprehension.  Well, I only have 10000 right now
The Kelley Blue Book value is 16,500 so I would need at least 12,000 and I can give you a month to come up with that. 
If you fill it up before I get it I'll do it.
