Most really good haulers are filled up about 6 weeks in advance. Check out the haulers on the H.A.M.B O'Dex (think roll-a-dex card file) here
http://www.jalopyjournal.com/forum/f...a-m-b-odex.12/. Those with good reviews include BenD, RacinRick, Bill's Auto Transport, Freighter Jim (on Ahoooga) and Passport Transport. Don't pick on basis of lowest price. For $100 dollars or so difference, pick on reputation. Think about a tip based upon their communications with you, their courtesy on both ends, the distance travelled, the condition of the car when delivered, their ability to meet their chosen delivery date, etc. Go enclosed: you don't want a roadster with the top or wind-wings ripped off, etc. These comments are not meant to slight other haulers whom I am not familiar with. Good luck!
