I fitted mud flaps to my Panda and I'm wondering if they're worth it. Fiat normally only allow rear guards, which are fine since they screw into the plastic bumper, the fronts are from the (2008-) Ford Ka. However, I've been reading some real horror stories about dirt and grime which gets behind them and corrosion begins leading to rust and in some awful cases, holes in the bodywork. Would you recommend mud flaps on all cars, or is it something you would avoid altogether.
