I'd say 4 cyl because of my long commute, but it'd have to be turbo'd for more powah
Cool last yr of the boattail Riv's w/ the 455 grunt.Can't vote on this one. Some nicer new cars like the Fusion don't come with anything BUT a 4cyl.
My first car was a 1973 (which I bought used in 1984) Buick Riviera with a 455. Hwy mileage was 12 mpg. Couldn't afford something like that anymore. Then I went to 4 cylinders. Then to V6's. When I went to a V6 I stayed away from 4 cylinders because they just weren't as smooth or quite as a V engine. A lot has changed. My Focus while still not quite as smooth at times as a V6, It is quiet. That is, I don't hear engine noise in the cabin. Big difference from 4 cylinders of the 80's and 90's.
