I got my car shipped too (from Texas to Washington). It was actually a lot less scarier than I thought, but then it was probably scary because I psyched myself too much from reading the bad reviews. It wasn't like what people reviewed online.

It was totally hassle-free from the pick-up all the way to the drop-off. Everything we agreed on the contract (including the amount I paid online) was everything I needed to know and do. No extra fees or hidden stuff, which I was definitely relieved.

Anyway, yes, you can pack your stuff into the car. I packed all my kitchen gadgets/ cookware, clothing, and books in my car. They were in the same condition I left them in.
