That is a pipe dream.
How about go down look at the car when the Expert is available during the week. If you like it give the seller a refundable deposit and maybe a rental "fee" contingent on the Miata experts inspection. That way the seller doesn't have to do anything and you get some seat time in the car to check it out.
Worst case for the seller is they don't sell the car but gets some rental money and the report showing what it needs. And best case they sold the car.
I'd take it to the Georgetown location if possible since it is a bit closer to Kileen.
