Super Monitor

[sportriderseattle]

Yes, you are correct, it only came on the 87 and 88 model years in the USA. I'm not sure about the other countries. I believe I recall seeing somewhere that it was about an $800 option and I have it on my 65,000 orginal mile '87 Turbo. My mileage has been averaging about 17-18.5 mph, but that's mostly with city (Seattle) driving. I have not taken it on a long trip yet where I consumed the entire tank fully on the freeway, but on some of my longer trips...say 1/2 to 3/4 of the tank used on the freeway and the remaining city driving I averaged a high of 19+ mph. Oh, and btw, this is a completly stock MKIII.

and for the guy who didn't know about this option, the monitor also has elapsed time and an oil change menu. I couldn't imagine attempting to use the elapsed timer while doing any high performance driving as the buttons are not in the best location.
