The service and the representative was excellent. Very easy to communicate and answered all my questions. It was a 2006 Scion TC, the transportation was fast, about 400 miles (not sure what route the transporter used, but on Gmaps its give or take 400), the car was fine.
Problem: The problem to me is that i got a quote a week earlier from this company for 1.5k miles and it was for about 850-900 dollars. When i got the quote for the Houston to my city (only 400 miles give or take) it was for 500 dollars. I pay the driver 300 when he delivers the car and i payed Magic Carpet 200 dollars. The amount i paid just doesn't seem right to me, but its my first time so i just did it. Although, paying 200 dollars to Magic Carpet and 300 to the transporter is where i'm confused. Why pay so much for finding me a transporter? With the quote for 400 miles, i should be able to get 1k miles added for about 400 dollars if you compare the miles or maybe what i payed should have been lower?
