I owned a 2008 A4. The interior is great and I would expect the 2009 to be as good. That would be the only area where is really stands out for me above the Camaro. Add the AWD in the winter if that matters to you ,but all other areas I would vote Camaro. The A4 does not really standout much ,but of the German sedans the Audi's are my favorites.
