I bought a car online - they took a 1k CC deposit. They didn't want to take more but I didn't really press them too hard - used a cashiers check for the rest of the DP and pre-approved financing for the rest. I did get outside financing for ~20 months rather than pay cash so I have the flexibility to pay utilizing manufactured spending techniques (VR, etc) to make the monthly payments or simply pay from my bank account. Works well since I'm able to hit spending minimums on new cards and not simply load up an existing card and further bolster my credit with an installment loan. No reason not to IMO with interest rates so low (and other investment opportunities)

Every dealer I have been to will take a deposit and up to 5k on a CC. that's it. and I pay the rest off with a check
Regardless if you are planning to pay it off at once, they still would not take it. They actually prefer if you finance.

$5000
 

We bought a new Lexus in May, and the dealer allowed $5000 on credit card and another $5000 on debit card. Worked great for us as we have the Suntrust Delta card.

For the balance due, I took out a loan and am paying it off in large lumps over about 6 months via Bluebird.

Got a used Tucson a few months back and paid 3k on CC then financed the rest so I can pay off with Bluebird. This has been very helpful in meetin multiple min spend requirements. In my mind, I'm getting more than the cost of the car in airline tickets and hotels.....does that count as a free car?!

Definitely a sweet deal if the car is reliable and the insurance cost isn't excessive.
