We have recently bought a new 2005 Prius. I have a question regarding 'breaking in' the new car. I have heard from people in the past that the new cars should not be sped. One of my neighbors who recently bought a Prius was pretty conservative about this matter and he said, he wouldn't drive over 55 MPH for the first 1000 miles. The car sales person tells me not to drive over 65 MPG for the first 500 miles.
I really appreciate if someone can explain the science behind this (layman terms if possible) and suggest the 'right' manner of 'breaking in' the new car and also if there is anything special about a new Hybrid car.
