Here is a suggestion that might cost a little more but it might be worth it in the end.

Rent storage for the vette and drop the insurance down to just cover the stored vehicle. The cost of the insurance just might offset the cost of the storage. Then go for the '32. Then, in a years time, if the vette isn't "begging" to be driven, sell it without regrets. Also in one year, the market will likely be better and a better prices will be out there for the vette. By doing it this way, you get a chance to feel what it is like without the vette and have room for the '32.

Just a thought.
