If you could sell your CS to a private buyer and then shop for maybe a loaner car that a dealership was selling with 4-5 k you may be able to come out cheaper.

I have driven Base cayman loaners and I would consider one next time if finances went south.

It was quite a shock going from a base cayman loaner for 3 days back to a CS with mods(315 HP). You may want to really think this one out before doing anything.
