Ive just came from the s4 avant and although quick and very capable ive got to say i would go with a bmw anyday of the week, after living with the audi for 6 months the build quality started showing, that old saying they dont make them like they used to.
Ive had a few german cars now and some people swear buy their reliability were i have had the exact opposite with them.
Dont go with any auto boxes either as ive heard a few kicking out big bills.
My advice go jap dont look back.
Adam your more than welcome to have a go of mine and see how rewarding they are to drive through the twisties
