Looking for some information

Hello I am college student and I am doing a case study for a trucking company and was wondering if I could get some first hand accounts from drivers about lease purchase programs.
What is the average weekly driver income and average weekly miles? What do you think the average industry turnover rate for Lease Purchase drivers is?
What would you think a percentage would be of drivers who actual complete a lease purchase program and become an owner?
Also what is the general attitude towards the lease purchase program? From what I have read on other sites is that if it's done right it is a good program but I've also read there are a lot of scams out there.

I realize some these questions could be a little personal but I am really just trying to get a feel for the overall industry. Any replies would be greatly appreciated. Thank you.
