I went to the local AAFES and got a quote on changing the spark plugs in a 99 Chevy Astro(or Safari) van. They wanted 3 hours of labor to get it done. This is a very easy job that I think almost anyone could do so don't waste your money. You just need the spark plug socket, ratchet, and a couple of wobble extensions for the plugs. Now to get to the plugs you have to jack up the front, remove the wheels and the fender skirts on the front. It took me an hour to complete this job, and saved a bunch of $ doing it myself.
Don't be ripped off, it is way to easy to complete yourself, or have a competent friend help you out.
