Hello,\n\nI recently  made a reservation with Mammoth for the F650.  The event has not yet taken place but so far there has been good communication.  After having difficulty booking with another limo company, Mammoth so far has done what they said they would do.  They emailed my reservation within 24 hours and it had all the correct details.  I will update this post upon completion of the event.  Would love to hear more feedback out there too from anyone else using Mammoth.  Stay tuned!
