So long as she treats it gently (easy, gradual acceleration and braking - no jackrabbit starts/high-speed driving, etc.)
Unfortunately that is a habit that I am trying to get her to realize. Lately she is doing better, but she still "guns" it every now and then and when I am with her in the car, I have this need to "go off" on her and exercise this desire. I think she is getting it

, she is clueless when it comes to mechanical stuff and often times thinks I don't know what I am talking about but I did learn something married to my ex and his father, If it makes a noise stop driving and check it out. From my Grandfather I learned to always check the gauges, everytime myself or one of my sisters went anywhere he would come out check the oil, water, gas level etc., he never wanted us to go anywhere unless this was done first, when the gas level got to a half a tank, he would go fill our cars up. So by example I learned.
