Put some Royal Purple Synthetic Oils in the engine. Get some royal purple oil for the trainy and the rear end. Get new tires or rotate the one you have depending on condition. Put a CAI and if you dont feel like purchasing one or already have on put a new filter in. I think thats good for starters
Well...it's a good idea after certain mileage. Not only will it help performance, but I lost my #1 cylinder due to a bad coil in rush hour in downtown Orlando; not the best feeling ever.
I will agree that 60k doesn't require more than maybe an oil change. I think I had my transmission flushed, but I was hard on my car.
Clean your intake/throttle body... getting rid of all of the carbon buildup. Other than that, it depends on how the car has been driven... if driven hard then definitely make sure everything is in good condition. For the most part these cars hold up very well past 60k if driven respectfully...
