In my 94 eldorado I sometimes get a civic and occasionally a mustang that wants to get embarrassed on the highway. I have had the car to ~150+mph in NC. On my way to bike week I cruised at ~120-130mph for about 30-45 minutes. I never got an overheat warning on smelled anything. It performed great and just as smooth as if I was driving at 60mph. Is it as capable of handling these speeds as it seems? What problems could I be looking at in the future?
