I believe UT in Austin has one and talked to a few people, cost would be about 15-20k to rent it for a day. Issue is between setup, teardown, creating the airflow you could really only get 3-4 different cars on.
Which would be good if you had them all setup ready to go ahead of time. Say:
-Stock Coupe
-Stock Nismo
-Modded Nismo with front/rear air diffuser
-Modded coupe with front/rear air diffuser
But who wants to donate money?
