1) Dealers put a max you can charge on a card.
2) It is not a limit by the credit card company.
3) We did ALL of our car purchase on a card.
. . . went to dealer on last Tuesday of the month
. . . this is the best day, as month-end, and Tues are slowest day
. . . went 1-hour before closing
. . . kept talking PAST closing time
. . . they knew they had a deal
. . . but, without credit card, we were walking (and we meant it)
. . . they let the whole amount be on the card
. . . they did want to lose a deal "they" worked so hard for
NOTE: The "last Tuesday of the month" and "near closing time" is
a well published purchasers trick. And, it works almost all the time.
