It’s been a few years but I used U-Ship to transport a WRX from NJ to ATL. I had zero issues and the bid I received was less than what I was expecting, especially since the engine was considered damaged so I asked the driver to not start it until I got it home.
I work for a Porsche dealer and all of our new cars are delivered via Reliable. For as many cars we receive, they do an awesome job of not damaging them.
Me personally, I would make a road trip out of it. Take the wife and family (if you have one) and pick a few highlights that you can stop to see on the way back. My wife and I prefer to buy cars out of state for this reason.
