FWIW, the last car I had shipped to me was 2 guys driving a 1 ton dually(I think a Ram 3500) with a 5th wheel trailer that looked it could hold 3 reasonably sized cars. The car I had hauled was small and not running, so they'd wenched it up to the very top of the trailer and when they arrived had get one car off before they could get mine.
It was also a bit interesting to see them deal with my car. Many old "LBCs"(Little British Cars) have fairly narrow wheelbases, and I got to listen to the tires scrub on the inside the whole way down the ramp. One of the guys sat in the car with the door open and helped push it down the carrier. They made pretty quick work of the whole thing-they had it unloaded and the other car loaded back on so that could make the next delivery-in about 15 minutes.
I got the impression that this was very much a small owner/operator company. I contracted with a broker out of Illinois for the delivery, and they arranged/paid the carrier. I was emailed the name of the company and a phone number, and I called to confirm expected delivery date/time to see if/how much I needed to take off work to be sure I was there for them. The lady who answered the phone answered with a simple "Hello" and when I said I was trying to reach(company name) she seemed like I caught her off guard and then asked if I wanted them to make their OTHER delivery in a town 50 miles away first so that they would arrive later in the day. I said yes, and they pretty much arrived within a few hours of when they said.
That was just one recent experience. It was a bit over $800 for Delaware to Kentucky for a small, non-running car. From playing around with quote estimates, not running but rolls/steers/brakes added about $100 to the cost. I paid the broker around $125 by credit card and then paid the drivers $700 cash on arrival(it was $690ish, and they couldn't make change-the only other thing they could take was MO, but it was worth the few extra bucks to me to not have to drive to the PO and stand in line). I'm GUESSING that the amount on my card was the broker's portion, and the amount in cash was the carriers portion. If I'd paid it all by card, it was closer to $900. 3 cars at ~$700 each for ~3 days work doesn't sound like a ton of money to me to split between two guys, especially given that I imagine fuel eats up a pretty decent amount of that.
