Input: Consider Input: Buyer: Hi I'm interested in your bike.
Seller: Hello. It's a great bike. It's a collectible. I'm wanting $180 for it.
Buyer: Ok, but I'm worried about the rust, do you know if it's gone through the frame?
Seller: No, it's purely cosmetic. A fresh coat of paint will fix that right up for you.
Buyer: Well it's a little more work than I care to take on. I'd like to get it for $90. I'm probably going to have to take it to a restorer.
Seller: It really won't need much work at all but I do have some wiggle room. $90 is just too low for the collector's item. I could take $160 for it.
Buyer: I'll bring my offer up to $110 but do you have a helmet I could have. Safety first and all that.
Seller: Ok. I'll take $110 for and throw in the helmet.
Seller: 
Buyer: 


Output: bike


Input: Consider Input: Buyer: hi there looking for a mazda
Seller: I have a great 07 CX-9
Buyer: indeed i see that you did all these great things to it. it seems to be in good condition. i am willing to pay 6000
Seller: 6000 seems a little low, I was originally asking 8k but after I had to have the brakes and rotors replace along with the other maintenance I had to raise the price. 
Buyer: the car is a bit old and it has very high mileage. I see that it has been taking care of however. Look my best offer is 7000k.
Seller: Age is not as big a factor as care taken. Miles were put on consistently over the years, oil changed every 3,000 by myself with premium grade oil and filter from the dealer. Lowest I could walk away with is 8200. There aren't too many other vehicles out there in this condition that low.
Buyer: I am afraid that we can't deal then.
Buyer: 


Output: car


Input: Consider Input: Buyer: hi your home is really beautiful 
Seller: Are you interested in the cottage?
Buyer: yes i am, but the price is out of my current budget, are you willing to lower it to 2450
Seller: I really can't go down that low $3,500 is a fair price can you make a serious offer?
Buyer: i was being serious, i mean it doesn't come with electric so i think my offer is pretty reasonable
Seller: Actually the guest cottage is the one that doesn't have any electricity if you look at the listing.
Buyer: ok 2800 can you work with that?, if i bring my own furniture
Buyer: 
Seller: That's still too low. How about $3,200
