OK, we're about to take the plunge and get a Prius for commuting between Kingman and Bullhead City, AZ. Temps in Bullhead can reach 116-118 and between our destinations lies a mountain pass of about 2500 feet. Obviously, it is a few degrees cooler up top, but still hot and often in triple digits. How well will a 2006 Prius handle this daily chore? Will I have any problems with this kind of heat?

Thanks.
