It will depend on milage since you vary what you do depending
on milage (they don't really call it a tuneup since not much
to tune, you just replace parts that wear and clean some parts).
May also be more if a previous service item was skipped.
Also, a dealer may quote $480 for the 30K service (price at
my dealer) but you typically need brakes and other stuff that
at 30K they can't quote until the see the vehicle.

Shop rate varies greatly by location. It's $135 hour at the
dealer and about $100 at independents where I live (and probably
lower every where else in the world).

What milage and where are you located? Someone here might be
able to recommend a good garage in your area or steer you away
from a bad one.
