It all depends on the area you live in. Its usually structured as a pickup cost then per mile. Last time I looked into it it was $100 for the pickup, then $4.25/mi.

I have a truck so a uhaul trailer rental is $50 and has unlimited miles. You can also rent a pickup and trailer combo from uhaul.

Don't forget, you need to figure out how you are getting to the DMV to register it, because you can't drive the new car.
