That's backwards to what many think. They are of the opinion that the 575M is too soft and is a worse car than the 550M it replaced. To be honest, I'd have to agree - they've even messed the headlights up.
For me, Ferrari haven't made a good car for over 30 years (or
Ferrari haven't made a Ferrari, as I put it), so the Vanquish is always going to be the better car to me. It made the 575M look plain on T.G.
