Pros
As a transporter you get to drive brand new cars around that just came off a truck from the factory. You also get to spend time with your co-workers, and if you like driving this is a fun and easy job to supplement your income.
Cons
As simply a transporter, I had no interest in "moving up in the company", but I could easily tell that while I was there managers were not happy at all. Senior management seems to treat everyone under them (especially transporters) like we were scum of the earth. For example, while on a valid break one day, the regional manager came in the break room and yelled at all the transporters in there demanding to know why they weren't working. They went on a hiring spree, and then had to layoff tons of us a couple years later.
