The more I think about the front fenders on the Elio the more problems I can see with the design. The biggest problem I can see is structural cracking from the road vibrations. These fenders are un sprung and will suffer from every bump and ripple in the roadway.
As Zipper said they do appear to be fairly substantial and not just flimsy pieces of plastic. It would be nice to see one unmounted to get a look at how they are constructed so we have a better idea of how well it will likely hold up.
