Somewhere around 2:00 am this morning I awoke and dressed myself in an assortment of cotton casuals then descended to the basement to drive my car. First however I responded to an email from Les Bell, Dealer Principal of Lincoln Heights Ford. He very kindly invited me to drive another of his Aviator models to compare to my vehicle what if anything leaked from its undercarriage. Meanwhile I continued my examination of the condensation from my own vehicle. Once again this morning I discovered that, upon moving my vehicle immediately from the parking spot (that is, without lingering to allow the engine to diminish the revs upon start-up), there were no collections of contaminants on the garage floor. When I allowed the engine to idle and then backed it into the parking space again, there were no manifest drips. Thus begins the comparative investigation.
