Task: Dialogue State Tracking
Input (English): Buyer: I am very interested in the bike you have for sale. Could you give me some information about it?
Seller: Hi there, I sure can. I ride semi-professional and I was recently sponsored, so they have me riding their brand now, I'm selling this one. I've taken great care of it, loads of upgrades from the stock model. Only weighs about 8 pounds.
Buyer: That sounds very nice. I am very interested, except I am a bit strapped for cash right now. I would like to offer you $1900 for it. That is cash in hand and I will pick it up today.
Seller: I could maybe do that if you have anything you could throw in. Do you have any bike parts maybe? I just popped a wheel actually
Buyer: I have a wide assortment of various tires and wheels. Why don't you run the bike by, and you can pick out a couple tires or wheels to go in with the offer.
Seller: Sounds perfect, I'll run the bike out to you tonight and we'll do the deal for 1900, sound good?
Buyer: Sounds great.
