It was as fast as the car felt safe. I could have gone faster, but above 230km/h (143MPH) the car increases speed slowly (then you would need more HP). And the second point is that the suspension starts to feel a little spongy. Needs to be harder/stiffer. But up to this speed it's real pleasure and fun to drive a crossfire! Especially accelerating from ~160 to 220km/h, when the AT shifts back to the 4th and the RPM go toward the 'red' ... what a sound from exhaust!!! Shame I can't overtake myself to hear that.
