I think it is so for the A4, but I'm not sure. Price is correct.
If your husband will have a lot of time, I recommend to visit the outlet in Marne la Vallee (he can go there by metro/RER - stop is the same as Disneyland; when he will go by car, is on highway at Reims, to the east from Paris). There may buy things up with a 50% discount.
