Live in the sticks, farms, mud and all that in thw winter! 1st thing I did when I got my A3, and the A4 before that. Recommend them as they really do keep alot of cack off the car. The front ones stop the mud gettring onto the door sill, hence you have clean suit, and your mrs a clean frock when you/she get in and out of the car.
Visiaul appeal, no issues for me, I've a red A3 with all exterior window surraounds in black, so belnds well in my opinion.
Easy to fit, you'll need a trolley jack and you'll need to drop the back wheels off too. £50 from Audi in Gloucester.
Can send you pix if need be.
