I would also change the oil and oil filter. After fresh gas has been run through to the engine I would replace the fuel filter and rubber fuel lines. I would also change the brake fluid and check the brake hoses at each wheel for cracking, replace if necessary. I would change the power steering fluid. I would change the trans fluid and filter if it is an automatic. Or fluid only in a manual. Change the differential fluid or at least check the level. Check all of the vacuum lines in the engine bay for dry rot. Check the spark plugs, at least one intake and one exhaust plug and determine if they should be replaced. Clean the rust under the coil packs for a good ground. Check your air boxes and air filters, and especially the blower motor under the cowl cover for rodent housing and or damage. Check the PSE for water damage and clean the drain. Lube all hinges. Check the tires for dry rot. Check the brake pads and calipers. Maybe turn the rotors if they have heavy rust. Change the antifreeze. Check all lights. I would change the fluids before driving it. Not saying that you need all of this. Just what I would do. Basically at least check everything. Replace as needed or as budget allows.
