You have a rather creative way on buying a car. In this case a Used car.

I would think very hard about buying a car with a credit card regardless of the rate. I tend to agree 4.9 for a used card is a good deal if that is infact that case as Tony suggests talk to MBNA and findout for sure the rate for cash advances.

A few other things you mentioned concern me too.

1. I would much prefer a regular loan to a credit card anyday. In 6 months that rate will jump, you didnt specify what APR that wil be then but It should be about 12 and less than 18 I would suspect. Then you be stuck with that balance at the higher rate. As opposed to a higer Rate loan with a fixed term to it. There is a trade off there and you might come out ahead paying the higher rate now versus the credit card rate for 2-3 years.

2. Using Stocks as a back up is just as risky. That money is/should be for Long term growth like retirement, education for kids - in general if you plan on using that money in the next 3 years (I think that is the rule-of-thumb) you prolly whould not have that money in the market. Rather it should be in a Money Market or maybe CDs.

3. You may really end up cutting your retirement money (Stocks) by a 4-5K to avoid finance charges. That is money that you really need to start building up to get the real advantage of Compound Intrest. It puts you that much further back.

Good Luck. I think I would look at what kind of Financing I could get with a normal Used Auto loan first. Also try not only the dealership (if its reputable) or a bank/credit union perhaps.

Please let us know the outcome. Like I said your solution is creative if not risky...
