you will not know what you need until you take the test. Best thing you can do is make sure it was all adjusted professionally at the last major tuneup and/or repair. if you have every done major work, make sure you have everything set to factory sepcs. If it is a problem engine with burning oil, messed worn our carb, and stuff like that, Chances are it will have problems. You just don't know unti you take the test.
Is it a Test Only center that the DMV is sending you to? I ssy always look for the best deal. Try to go to a place that will give a retest at a discount. if you can't get any deals, or coupons, like from the PennySaver, than at least don't go to the most expensice place. if it's a test Only Center, they cannot and wil not tell you what needs repaired if it fails. it' it's not a test only center you are being directed to at least they can tell you what failed. I fyou have any dash lights out, it will not be testable. California can be the test from hell on some cars.
good luck..
