    I've been looking at used Saturns, especially the SW2. Many of them are great,
    but don't have cruise control. Is it practical to add it? What's needed, and
    how much do the parts cost?

  3. I did the audiovox JC whitney thing. Worked, but was a pain. Had to mount
    the thing inside, activating gas pedal, as no adequate way under hood. Had
    to bring vacuum inside to make it work; would buy non-vacuum model if I had
    to do again.

    I wouldn't touch a vacuum retrofit with a ten foot pole. Electrical/electronic
    stuff is just so much more reliable, and vacuum leaks are a real PITA.

    Actually, I was hoping to find a factory-parts solution. You can install
    factory cruise control in a BMW pretty easily, so I'm wondering about Saturn

    They have a non-vacuum model - .

    I added the vacuum type to my car and it works ok. As soon as the road
    starts heading up the car slows and won't kick down unless I stomp on the
    gas myself. Once it has kicked down the car will climb back to the set
    speed without my foot on the gas and once the road flattens out it will
    shift back up again. I don't know if the electric ones have the same
    issue, but it's much better than nothing.

    It slows down most likely because the engine manifold vacuum is diminishing
    under load. That is, assuming that all the linkages were properly tightened.
    Many cars with vacuum operated SC used a combination of manifold vacuum and
    ported vacuum (from the venturi of the throttle body). The ported vacuum is
    zero at idle but increases with engine load.

    Not the same if an electric one is used.
