You are stretching equivalencies here pretty hard with regards to capital investment of a product vs. expectations but I'll play along.
If I was told this plainly and openly up front then I wouldn't buy the car to begin with -IF- that is what I value in that specific vehicle. My car? Not a chance, I like my sports car and working on it is part of the fun I get from it. My wife's people carrier? If those repairs are close in line with other repair shops even after the 30% AND they'll come pick it up or tow it so I don't even have to mess with it? Absolutely, where do I sign up? Different tools have different uses and value propositions.
