They didn't need fancy diesel cars or Sprinter Vans in the old days.
I did learn something while using my SUV to haul bikes. When I went on a trip, I took two small bikes with me. One inside the vehicle and one on the hitch mount. The smell of fuel mixed with two stroke oil was a bit overpowering and had to run on the freeway with the windows opened. Something to think about before you get a Sprinter etc.
