I have a brand new Traqmate basic system for sale. I bought it based on the current-at-the-time NASA rules, but the rules have changed and I can now use one of the other systems that I preferred. The only time I used it was right after I received it a couple weeks ago, when I put it in my street car and drove around just to test it out. This system uses GPS and accelerometers, with support for external inputs coming soon.
Normal price is $700 for this system. It also comes with an extra power harness for hardwiring the power input in a race car.
My price is $650 plus shipping.
