I wass talking to our Tech last night (had the oil changed and prep the car for a one day driving school next Friday at the Gingerman in South Haven MI) , and he said this recall takes about 20 hours of time to accomplish. Not a short one at all, so that is probably why the dealer is saying four days. Brackets have to come off the car, welding done, etc, not an easy recall. This one doesn't affect the Gen I cars for a change.
