From my expierience of owning both cars i'd have to say the au's handle alot better as the front doesnt lose grip as easy in the au's. Agree with kit on the engines, why make an engine with all it's power above 4 grand then limit it to 5500?? doesnt make sense and contradicts the theories behind having a quad overhead cam engine. If you love wank facter then get the ba, if you love good cheap motoring with average power get an au or if you love wank facter, handling and power get a t3
