I have owned this car for two years now and by and large have been satisfied with it. I was told by a trusted source that it does well on the highway/ gets good highway millege and having an hours commute have to agree with this source. Thats why I gave fuel economy only three out of five stars, it's a big car and purchased more for comfort then fuel economy. The shocks are excellent on the more potholed backroads highways. A passenger once described it as riding in a boat, a pretty fair example. The tie rods seem to be the only weak spot so far. As was asked by another buick owner if I experienced a shuddering going through the whole frame of the car, I told him yes I had, it was the tie rods which had to be replaced after only a year of ownership. If you don't mind gassing up more then a smaller car its a safe bet for a long distance driver.
