Yah right, you’ll be able to get it to that speed if you go skydiving with it maybe?
It would be an interesting experiment if you didn't mind wrecking the car to find out.
It's been a few years since I've done any skydiving, but IIRC terminal velocity for the average Joe is about 200mph. I can't help but wonder how the different shape/weight of the Fiero would fare.
