So because you mentioned it I just called them for transporting by enclosed carrier on the east coast between 2 cities. High end car enclosed carrier.
Intercity wanted $1995 for the same transport that the car dealer (a high end car dealer well established no less) want $1600 dollars for.
Intercity essentially said 'busy time of year etc etc'. Didn't give remarkable reasons why they would be better than anyone else. Picked up the phone right away and was otherwise business like.

Also their website to get a quote they want an 'auction' number. That made me call them (which I would normally never do.)
Additionally their price was higher than other brokers I had checked including the one that just moved a car for me (same route) not enclosed who quoted both enclosed and not enclosed.
Would like to point out that the job of a broker is not to match you with anyone but match you with people who they know and trust and have used. And specifically the broker I used (for the last open move) made a total of about $250 the rest paid to the driver on delivery.
