Probably not very good really. People will give you tales of how well they crashed in the most unlikely vehicles but thats not scientific in any sense of the word. Small volume producers dont go through the euro ncap tests so we have no good data.

But would you want to swap your morgan for the latest most crash resistant three door hatch? And would you want it equipped with the volvo collision avoidance / auto braking system which is another step forward safety wise?
