Whatever you look at, make sure you take it for more than a spin around the block. It may seem comfortable after a short trip, but after 20 or 30 minutes, can really feel horrible. Upscale cars like Acura or Cadillac may have the smoother ride you’re looking for, but you’ll need to spend a good deal of time looking at, and test driving, different vehicles.
Let no stone go unturned would be a good phrase to remember.
