Hello Everyone, have had the series 4 aero 2 weeks now and really enjoying it. in the last 6 years i must have had most of my dream cars from e types to quattroporte but the aero is quite a special car, tremendous power and lovely feel that i have not found in any other car, i could easily drive it all day long,but does any one know why when i raise the side windows they often produce pieces of sticky back foam stuck to the window, its like the car is trying to impress me with magic tricks
