Just came across this post and it is definitely very late by now.  Anyway, here's my 2 cents.
This would not be possible simply due to few factors:
1. As someone mentioned before, balance transfer on 0% transfer required an upfront fee that's typically 3-4% depends on the bank, so right there you have a cash outflow.   
2. The zero percent is typically a promotional rate for 6-12 months, after that the rate goes back to your purchase rate. However, CDs for the same duration are typically less than 2%.
3.  In order to keep up with the promotion, you need to make minimal payment every cycle. However, CD do not pay out until maturity and early withdraw with incur penalties.
4. Lastly, if you missed two payments, the penalites rate will kick in at cash advance rate, that's a killer.

Bottom line, It's not going to work.

ps. I don't quite understand one of the reply who bought Mercedes at 2% and and earn 3.5% on the balance.
