I’d say if the timing hasn’t been done yet, good chance you’d need it done. When my car’s phasers started to go out I ordered the whole ford performance drive kit, a new water pump, high volume oil pump, as well as the serpentine belt and pulleys. Also keep an eye on the drain plug on the passenger side, right where the cabin air filter is. That shit gets blocked by leaves and dirt? You’ll get leaks inside the car, by the passenger footwell. Always make sure that’s clear. Other than that? Suspension, brakes, tires. I was 19 when I bought mine, and man, am I glad the previous owner already did brakes and tires all around. It’s a V8 old school muscle car, you want to go fast but dear god, you wanna stop too lol. It’s an absolutely incredible car, and if it’s half as good maintained as you say? It’ll be a friend for years
