This is the reason one takes an out-of-warranty car to an independent

more muscle than intellect and so doesn't require the dealer's
(expensive) expertise, IMHO.
It may interest you that this labor rate, in $, is about what we're
charged in Northern California, but we pay 7.75% Calif. sales tax only
on the parts, not on the labor component.
