IMO, don't let the dealer rip-off you.
Never pay for a 'package service'.
Ask things separately. Oil/filter change. Ignore the cabin microfilter or remove it. Coolant change. You'll probably be pressurized to flush the brake fluid... if it was done at 2 years, I would wait until 6. Or 8 if it was done at 4. Air filter change (it is cheap). Alignment if you noticed something. NO INSPECTION at all. Ask for a price before bringing in for service. Spark plugs replacement would wait.
I would expect no more than 500$ if no alignment.
