I used this, walked in and told them what I was going to pay... and they sh*t bricks cuase I was an educated buyer.
Played hard ball till they gave me the price and rate I wanted, then when they thought it was all finished and they were wrapping up the deal (past dealer hours the night before a long weekend) I held out till they doubled my carefree mantaince plan and gave me the platnuim warrenty for free...
In short they were really mad at me
Good Luck
