If I'm not mistaken, most trip computers are a feature built into the car's management system. In other words, speed, fuel readings, and miles traveled are all added up by the computer and then displayed in your choice of readings.

If, however, you want a decent trip computer (you would still have to calculate MPG, but the rest of it would apply), I'd suggest a GPS. That way, you get distance, speed, I think average speed, plus a scrolling map feature, city database, trackback, waypoints, altitude, trip markers, and a lot more depending on the model. If you plug it in or wire it into the car, you can travel with it backlit for nightime use.

If nothing else, it's a functional, but cool toy to wow your friends.

The Garmin GPSII, GPSIII, and GPSV, all sit perfectly on the 940 dashboard, and are my favorite choice because of the landscape display and the vertical antenna that allows you to position it for good satellite reception. Also their backlight matches the rest of the panel pretty well.

Can you tell, I'm sold on this?

Starting at $115.
