I feel your pain! In my lower back after vacuuming out the car.
It is interesting how cars behave differently. My PT turbo, blows wind in my face (bad for contacts) and requires a second window open to draft all the smoke away, but no ashes inside! My tC, on the other hand, requires only one window open, does not allow wind to blow in my face, but leaves ashes everywhere!
My major bee-otch about the tC as a smoker's car is that rain comes pouring in if one has a window cracked just a hair.
But I digress.
Someone a while back posted a pic of a tC with the wind deflectors on. I don't they said where they were purchased. The car, IMO, did not look that great. I am waiting to see one in person before deciding.
Were I really hankering for a set, I would call several of the car companies that sell them and ask if they made it for the tC.
Keep me posted!!
