I had never used uShip before, but was referred to the site through Ebay after purchasing a car in CO through Ebay. I've been very pleased with the overall experience. Lots of information is available on potential shippers, including customer feedback which I feel is the most important aspect of choosing a shipping company. The company I choose, Nick Tuttle Services, provided an excellent shipping experience. My car arrived in the delivery window stated by the shipper, in perfect condition, and communication between myself and the shipper was excellent as well. The price was also very reasonable.
I would definitely use uShip again, and I'll also recommend it to my friends. Everything went so smoothly, I didn't get stressed at all! :)
