What do you mean by the Koeinsegg being better?
The Enzo is a amazing car; it's breakes and steering. It's super fast and can run on the track better than a lot of other supercars (I'm assuming not the McLaren F1). It's also got a bit of practicality in it, like air-conditioning, power-steering, power brakes, traction control, and other features; the McLaren F1 had none-of these features, nor did it have the launch control system the Enzo uses to help reduce tire-spinage at launch. The Enzo is also quite large, so all of these features and size add weight; power-to-weight ratio is important in top-speed so maybe this is why it didn't achieve the top-end record or a close time to the 0-to-200mph record.
The styling is aimed towards down force and air-management; it's very F1 like and Ferrari did this on purpose. Does it look good? It's all objective, but lets pleas not just judge a car by it's look, it's not nice
In my opinion, it's very striking/dramatic, purposeful looking (witch I like). It's not the best looking Ferrari, for I would choose the 288 GTO. Other super cars sure look better to me, and that includes the Murcielago for example
Now that I think of it, the grey color does give it a fighter-jet perspective whb
