I'm very familiar with that trip to Costa Mesa.
That's where my Shelby dealer is/er was! Newport Shelby is no-more.
Be careful on the 405/i5 interchange. Three freeways converge and you have semi's trying to cross 6 lanes of traffic both ways across all lanes!
And stay out of the tunnel at Santa Clarita!

P.S. My trailer has new tires & wheel bearings if you want to use it!
