Stop comparing quotes by the deposit amount, that's how I got burned by a broker in Reno
I compared four quotes for my move from Reno to Phoenix and picked the one with the smallest deposit, $150. Turns out that number means nothing, the real cost is the fuel surcharge and the pickup window fee that showed up after the carrier had my car. The broker was listed on a site I trusted but had no actual trucks, so my car sat in a yard off I-80 for 9 days waiting for a carrier. Check who owns the trucks before you compare anything else, has anyone else been stuck waiting on a broker like this?
A buddy of mine went through this exact thing last spring, moved from Sacramento to Tucson. He picked a broker with a $100 deposit because it looked cheap, and his car ended up sitting at a lot in Stockton for almost two weeks. Every time he called, the guy gave him a new story about a carrier being lined up "any day now." The fuel surcharge alone added like $280 to the final bill, plus a $75 fee because the pickup window got pushed back twice. He finally got his car but swore he'd never book without confirming the company actually has its own trucks.
