I most recently used Horseless Carriage
http://www.horselesscarriage.com/ They're based in Paterson, NJ but ship coast to coast in enclosed trailers. Great fast service -- competitive price too!
NEVER USE PLATINUM LINES. THEY STAINED THE INTERIOR OF MY BUDDIES BRAND NEW 50TH ANN. VETTE -- PAID FOR NOTHING. THEY ALSO DO NOT COVER THE CARS WHEN THEY ARE INSIDE THE TRUCK AS A RESULT I GOT A WHITE POWDER ALL OVER THE HOOD OF THE CAMARO. DID NOT RETURNS CALLS. BEWARE!
