If it was me in your shoes, I'd hunt for an ERA. (Or contemporary ccx).
Quality cars with a tight supply line therefore prices are likely to stay stable or even see an increase.
Only issue you'll have is finding one am ERA for $40k.
But, the game you're playing is all about your buy in. ie: the lower you buy below market value the better your chances of seeing your money returned to you on sale. This will be true for any kit you decide to purchase.

Good luck with it.
