$100 takes it.

Some specs:

The Rev/Speed Meter is a monitoring instrument designed to measure engine RPM, vehicle speed (km/h) and provide stop watch functions. RPM and speed modes have a peak hold function. Stop watch functions can accurately record quarter-mile elapsed times, 0-60mph and 0-100mph elapsed times, as well as other user-defined elapsed time measurements. It has the same look as the popular S-AFC II, and these 2 go quite well together in the interior of your car!
