ouch! That's just a silly number. Even at something stupid like $8 a quart plus filter your looking at less than $70 for parts.
I know when I had my corvette I would bring my own Mobil 1 to the dealer to avoid the 100% markup on it and they would charge labor only, like $20-25 at most. Even if they drop the skid plate on the H2 your looking at a half hour job.
