James, It's going to be great to finally meet you and see this car in person! I've been fortunate enough to be able to see one doing a few laps around the Homestead track in Miami. I believe it's the same car that has been maintained by Shelton Ferrari Ft. Lauderdale. The sound was amazing! -Augustine
