I'm foolishly considering looking at this car. It has a stand alone engine management computer that does not communicate with the systems computer of the car (hence the warning messages in the video). It is heavily modified but the owner states that it works well and does not (yet) suffer from the shifting issues common to these cars. He is asking about $28K. Any thoughts?
