Nearing my fifth decade on this planet, I have NEVER financed a car.
However when I do go in to haggle, I *never* give any inkling as to my intentions to pay in full, so they have visions of finance profit sugar plums dancing in their avaracious heads .
I do ask, "So, what does that come out to for the car itself... not including the financing?" (I've already looked up the 'Blue Book' value before I even walk in)
When I decide upon a vehicle and Mr Sleazeball sets me down in the mind-warp chair to manipulate my dim-witted female brain into compliance, I typically walk out at least once when he gets to the add-ons, or when his "manager just won't approve such a low price,", etc, etc, etc with "Sir! I won't be wasting any more of your time! Good day!"
After he either runs like Forrest Gump to corral me in the parking lot or if I escape, calls me at home to, come "talk" some more... and he FINALLY gets realistic, then and ONLY then do I whip out my checkbook and announce that I would prefer writing a check for the sake of my records, but if you can give me $500.00 MORE off, I'll go to the trouble of getting you good green cash straight from my bank."
The overwhelming majority of car salesmen are masters of manipulation who 'profile' females to the max, and I thoroughly enjoy messing with them like nothing they have EVER encountered who of my gender!
