Re: be driven to and from work by IBM personnel in a car leased by IBM
Probably doesn't make sense given she probably has several pool limo's at each site except her home base. Plus other execs probably get to use it when she isn't.
Given the size of the IBM car fleet they probably get better discounts on adding a few more cars to the leasing fleet than buying a few outright in addition. Plus then you have to deal with separate maintenance agreements and the like.
