expect either side of $500.
typically kia does four stages of service. a 1 is simple oil and filter change and they inspect the obvious things like tread wear and brake pads depth, rotate your tires if applicable, make sure lights are working, etc. costs anywhere from c. $50 to shy of $100. my no. 4 inspection last fall was over $1,000 and I still feel raped - the previous 30,000 miles inspection, a no. 4 also, had been over $700 which felt at the time was pretty expensive. your mileage will put you at a no. 3 inspection, which includes everything in a 1 and 2 plus "other stuff." the schedule goes something like 1 2 1 3 1 2 1 4 and repeats every c. 30,000 miles.
