I would tell him like this. Rent a storage unit. Get all his stuff in it and give him a ride to the airport. Or get him a u-haul load it and send him on his way. If he cant drive it he has to hire a driver with a one way plane ticket back. This guy sounds like he could be a cheap mooch.
Is it mostly the request to use your car? I absolutely wouldn't allow that because that's a nightmare waiting to happen. As an attorney he should know this. Is it more than the car (him staying at your house while you're not there also?).
