I was on a ride today with Will DeGroot from Exotic Cars in NJ and he had his new 550 with him that he just flew out to San Francisco with his wife and drove home in 4 days. No issues! 3200 miles.
I bought my car sight unseen from a famous musician in Nebraska. Flew out one morning, took possession of it from his son, then drove it back to Michigan - and it was in rough shape. Engines on these cars are strong. Drive it, you'll be fine.
