Are there any 3rd party or import oem mud flaps for the C? It seems that going any over any sort of small puddle, or even water that has collected in the dips in the road (like the one right outside my house) will splash dirt all over the side of the car (and I try to drive really really slowly over them). It's especially annoying when after a car wash and the tires are still wet, and you drive off and 10 minutes later you find dirty water all over the side of your car!
Unfortunately no, at least not yet. Toyota moves at a snails pace when it comes to add-ons and I agree with you, the C needs them. I Do wish the "aftermarketeers" would produce a set. FYI, the Yaris mud guards won't fit the C. I already explored this possibility.
