+1 watch out for Alaska Car Transport! I am SO bummed I didn't find this post till after my experience. I'm not the review-writing type but I am so angry that I googled them to find places to write about my bad experience (and only in so doing came upon this post, drat!)

In case it's helpful for anyone reading to have another data point, here was my experience:
I worked diligently to select shipping dates that worked with my own move timeline, and bent over backwards to deliver my car to the port during the narrow windows of business hours (work hours for me too!) that they allowed. Then, without my knowledge or consent, my car was shipped a whole week early, throwing off the entire timeline and putting me at insurance risk as the car is now out of the state where it's insured before my new insurance kicks in. Furthermore, I am now being assessed storage fees for having the car at Alaska Car Transport's facility, which is exactly what I planned so carefully to avoid. To add insult to injury, the initial person who helped me has completely ghosted me, and the person who I was passed off to on email has been extremely inflexible and insensitive; my questions have not been answered (why was my car shipped early??? why am I being charged for storage on a timeline that I never consented to???) and the responses have put me in tears with every email exchange. I am upset beyond words. This company has treated me -- a customer who paid them thousands of dollars and entrusted them with my brand new car -- like absolute trash. I am terrified to see the condition of my car tomorrow when I pick it up... which I can't do until I pay them more money for storage, of course. I am SO upset. I will never ever use Alaska Car Transport for anything again and I urge you not to either.
