No wayyy! I see you are doing other hot laps on the Nurb, I can't wait to try these out aswell like the Turbo 5 for instance which is a really cool car!
yes it is, i have completed numerous races in sardegna with the restrictions you have given and i regularly use it for money grinding. the only advice i give you is that if you do this to the mp4, only go to second gear while going round corners or turns. the acceleration is greatly decreased by shifting to first gear so that's all i recomend
