Update on Car Repairs

We got the water pump fixed on our main car... and found the leak of power steering fluid was coming from the 'rack and pinion', and expensive fix. That we got repaired last week as well. It's only money Honey I kept saying as we paid the bills. Then the 'check engine soon' light on the new car lit. Not good news. That was an O2 sensor malfunction. As repairs go that one was not as costly. I am wondering though just how sensible it is to have cars under the control of computers, after all. The good news is the repairs are all said and done...and there will probably be no more for some time. Like maybe until tomorrow?
