Agreed, this is were I got to when I walked away. I priced warranties on the car: dealer ($6K for 4yrs/50K miles), and a couple of others in the $4K to $5K range for 4yrs/48K miles . If someone is interested I can send you the warranty info/pricing. When the deal ended for me was when I told the sales manager the car's wholesale value was $18K to $19K and we would need to determine how much the cleanliness of the car is worth. At the time his answer was $24K and in my mind I could not justify a $5K investment over wholesale, plus warranty $4K and be upside down in the car by $9K the second I drove it off the lot. This in conjunction with their attempt to under value my trade initially in the deal just put me off. So in the end, if they keep getting enough offers on the true value of the car, they are going to take one of them as I believe they are near the tipping point and desperately want to cut it loose.
If someone is interested and can tell me how to tell if the TC is blown, I would be happy to go drive it again to figure it out.
