Teenagers / Classic Cars ??
Well let me say this about airbags. My wife and daughter were hit head -on back in 2000 by a driver who passed out behind the wheel and crossed the centerline at over 60 miles an hour. They were driving our new 1999 Ford Contour with less than 4000 miles on it. The car was destroyed and the airbags saved their lives . I am thankful that my wife chose to leave her 80 corvette home that day as they probably wouldn't be here right now. My wife wouldn't drive the corvette again after that and she won't ride with me in our Mopars unless they have upgraded seatbelts. Things can happen to anyone, driving anything , at anytime. The best you can do is educate your daughter the best you can, prepare for the worst and hope for the best. Good luck with your decision.
