If its cold, i.e. your taking the car out for the first time of the day, i rekon let it warm for bout 2-3 mins, like you dont sit there with a stop watch, letting it warm for like 5mins plus, is just unnecessary. but i wouldnt go hitting 5-9grand on a cold engine, its just asking for promlems later on. dry steering is bad news. But with these sportivo's i think everyone would agree that they are made to be revved, hence the compression ratio, and two they are toyota :)
