Um, why not fork out $40 and buy the manual for your car? Read up on what you think might be the problem? If you take it to the dealer (stealer) then you might get shafted. Some routine maintenance is required but there's nothing that sayz you can't do that yourself. With few exceptions, you can do it all yourself. Find a user/netgroup that owns your model and year and the will overload you with DIY info.
Otherwise, join the rest of the sheep that flock to the stealer to have their cars taken care of.
