Why wasn't the car working properly when I bought it certified?
Why did the car stink of fuel when I first put fuel in it?
Why did the headlight have liquid in it which they told me was "just sweat"?
Why were these things, sold as a certified car, not addressed BEFORE i got the car?
My guess is this- perhaps it was difficult for them to fix it beforehand but after being bought, they send the buyer away and when there are problems, the buyer has to waste time and effort but the dealership bills the warranty company? This way no issues for them and profit from the warranty service? Could this theory be true?
