If it's a company car, you don't need to be concerned with problem areas such as dual mass flywheels, diesel particulate filters, EGRs and timing belts. You'll only have the car for three years and the poor sucker who buys the car after your tenure will be the one who has to pay the big bills. When the public finally cottons on that 3 - 6 year old diesels with DPFs are potential money pits rather than money savers we are going to see a severe dip in used diesel retail prices and hence in diesel residual values. Hybrids are proven to be much more long-term reliable. Nothing much ever goes wrong with a Prius.
