The Auto Transport business is quite varied as to the rate per loaded mile depending on many factors. Most cars go at a bulk rate (that's why you see 9 to 13 car haulers), some go at an expedited rate, and others go for what I like to call the, "off the beaten path rate. " A seven hundred mile trip say from S. California to say Texas is not going to pay as much money as a 700 mile trip from S. California to Utah. The S. California to Texas route (Interstate 10) sees a lot more traffic, hence a higher supply of Auto transporters and a lower demand for price. Another factor is the time to get the shipment from point A to B. Obviously a 700 mile expedited run (1-3 days) is going to command a higher dollar amount than a no guarantee of delivery run (7-10 days). A few other money influencing factors can include the price of the cars (more expensive vehicles require higher amount of cargo insurance) you get more money hauling Vettes & Porshces than you do hauling Toyotas, older cars etc. You get more money hauling enlcosed vehicles than you do open trailer. Inoperable vehicles command a higher price than do operable vehicles. Corporate moves generally pay much higher than Joe off the e-bay. Inclement weather & specific locale can also be a tremendous influence in the price of the vehicles being shipped. Some areas are visited not at all by the bulk transporters, especially when it is winter.
My current trip is from S. California into Bozeman , MT. (yes there might be snow on the road) will gross $2675. 00 for what is approximately an 1,100 mile trip & that works out to about $2. 42 per mile. My return trip (S. Montana to S. California) will earn a little more ( $2795. 00 or $2. 54 per mile)
Round trip $ 5,470 dollars gross minus 440 gallons of fuel @ $3. 00 per gallon = $1320. 00, minus insurance $846. 00 per month, minus monthly cost of truck, minus maintanence, minus food, minus time away from home, minus a hundred other things still equals a pretty lucrative operation IF you can pull off 4 round trips like the one described above per month.
Pulling cars to and from the Auctions is possible, but probably not very lucrative because there are so many companies competing for the Auction hauls.
It pays to specialize, my specialty is off the beaten path in Utah, Idaho, Montana & Wyoming. One guy I know does quite well hauling enclosed, another handles exclusively inoperable classic cars.
I never run deadheaded except for occassional 100 to 200 mile stints on the "off the beaten path" runs.
This business takes A LOT of cash flow for fuel, maintenance, food, & the unexpected.
A second truck is almost a must because if you have a major brakdown you need to use the backup truck to keep the cash flowing otherwise you will get eaten alive by downtime.
There are many licensing, State and DOT type issues.
There are tax issues.
There are legal issues.
There are butt pucker factor issues because it's snowing & some dimwit just cut you off. :-laf
It all adds up to yes you can do it but look long and hard before you leap so that you will be prepared for success.
