I'm not a big fan of Ruf. Sure Ruf is qualified to be considered as a manufacture by German transformation officials but despite that fact Ruf lacks the same build quality of a Porsche-built 911. And unlike Porsche, Ruf does not have the same budget to commit to all-condition testing that Porsche commits to. Even though the car look is a Ruf-built 997, Ruf currently does not own the M97 engine, which means it is using the same 996-GT1 engine.
