Ok, what about brakes, wheel bearings, axel wear, shock/struts, etc. I am not only considering the engine>>>

Brakes: Brakes that sit for periods of time without regular use can have problems with sticking calipers, to name one.

Wheel bearings: Can sieze. I had this problem with my 81 Civic which I bought with only 59,000 miles. Although the car is still running strong today, I initially had to put a decent amount of work into it.

Axles: Ruuber boots can deteriorate, crack open and allow road debris to destroy the axle. Axles generally don't 'wear out' People forget to check their boots, they split open and then it's just a matter of time before they start clicking when they make a turn.

Shocks/struts: Struts can develop leaks.

Exhaust system: Will rust.

Belts/hoses/tires: Will dryrot.

Fluids: Will deteriorate as well.
