Data Point: Buying used car this past weekend, at a dealership. Mentioned that i would like to pay as much as possible with CC then use a personal check for the rest. Salesman said usually they let $5,000 on the card; which i was expecting so OK.

Then get into the F&I office and for whatever reason they didnt seem to like the check idea. He asks if i can settle up with the CC today for full amount. Obviously say YES! I think they were kind of hoping to call a bluff in some way and get me on a short loan to get out the door (5pm on a Saturday). Obviously my Biz Plat didn't sweat $22k. In and out in under 2 hours including test drive.
