Good that they're taking responsibility. Again, I stress - the help you get in this situation is 100% down to what you ask for, and how much you push. They want to give you nothing extra, and for you to suffer silently (nothing personal, it's just the way business works). I'd be calling daily, politely pointing out that I am without my sports car due to their error and that I am unhappy and would like a resolution ASAP. - MENTION the owners/drivers club forums. I would push for a GT86 courtesy car, personally. I would point out that the only acceptable alternative would be an immediate lumpsum to cover the market value of the car plus a fair daily charge for time without it to-date - so you can return yourself to the situation you were in prior to their mistake.
