In my opinion, I wouldn't go with the dealer for financing the car, you'd be better off getting a personal loan from your bank. That way, you can hand the dealer cash (huge bargaining chip), and any money you save can be repaid straight to the bank, which can nip your interest early on (most banks have an early repayment fee, but their policy doesn't cover paying over the repayment amount and having a debt of $1 for the last three months of the loan). Dealer finance will bend you over a log on most occasions with heavy interest rates, and because they're selling it to you on finance, you will have a hard time negotiating a price.

Talk to your local banks and see if they're willing to loan you the sticker amount of a 300C. Work out your repayments and interest, and consider that vs. a dealer finance.

As mentioned, if you aren't desperate to get an '08 model, you can tear the dealer to pieces in negotiations for an '07 (make frequent mention that the car has been sitting at the lot for an entire year now. Ask how often he's let the motor idle for 20mins or so to stop the engine siezing. 9 times out of 10 they'll uhm and ahh nervously)
