I just listed a first generation ScanGauge 3-in-1 Auto Computer on eBay. It is in perfect working condition with virtually no wear, scratches, etc. The attaching cable with OBDII connector is included.
A new ScanGauge costs $159. Mine is starting out at a $5.00 opening bid with NO RESERVE.
I purchased it brand new and it has always been in my personal vehicle. I’ve had it for about 3 years. These things are awesome and I can't imagine not having one in any of my cars. The ONLY reason I’m selling it is because I decided to upgrade to the smaller ScanGauge II model.
Velcro has been attached to the bottom of the unit, so all you have to do is attach a strip of Velcro to the mating surface in your car and stick it down. I will include some adhesive-backed Velcro strips with it, so you don’t have to buy anything else to attach it to your car.
There is no special wiring involved to hook this unit up. You just plug the cable into the OBDII connector under your dash and that’s it!
