Unusually low rates. By comparing prices, you'll get a feel for going rates. If your quote seems inordinately low, ask the carrier why. Odds are, they're compromising on service.

Unusually short delivery times, or a promise to pick up the car without a contract. Some companies may give you a verbal promise, over the phone, to pick up and deliver your car. Without a contract, that company could choose to pick up just enough cars to fill a few departing trucks, legally leaving you behind.

Unconditional cancellation fees. This could be a charge of up to $200. If you agree, even if the company doesn't pick up your car, you can still be charged the fee.

"Fully insured. " Never take anyone's word for this. Always obtain a written contract, and carefully read the terms and conditions. All America provides full primary insurance.

Short time in business. Some companies change names (or ownership) every year or two. Some even go by as many as five different names. You can find out how long a company has been in business by their federal license number. Any license #300-000 or above tells you they have very little experience. All America's federal license number is #184-386.
