Any powerful machine will bite you in the arse if not treated with respect.
Just like the Plus 8 you have to show some respect with the stop and go pedals or they will catch you out, you have to experience a few tail out moments to learn this though.
If they sounded like a Plus 8 I wouldn't hesitate in owning one, I tried a 3.0l Roadster but didn't like it so went back to the 3.9l Plus 8 at 190bhp it has enough power to thrill.
