As far as I can see, so does Pope Francis. A priest should have transportation that will allow him to perform his duties efficiently and safety.
My pastor has an Audi sedan, very safe and reliable. I think his family bought it for him. Some priests can walk or use public transportation or rarely leave their missions, and don't need to have a personal vehicle at all.
All of them - and all lay people, too - should be asking themselves, "Is this good stewardship? Is this apostolic?"
I’d ditch the Audi and put him in a Jeep, even more safer, reliable and less expensive.
For a priest who has to drive around a lot - a big parish, or several parishes - a good quality, reliable car makes sense.
I can see that the optics of a high-end luxury sedan or sports car are bad, and it also is not as useful for hauling a bunch of parishioners or sisters about, not to mention the new washing machine for the rectory . . .
But I can see a high-end SUV or crossover because of the versatility, reliability, safety, and comfort. You don't want to be in a bouncing tin can if you're on the road for a good part of the day.
