That's a steal!!
At ~240k, honestly, my main concern would be the transmission if it's not been replaced. That's on the high end of the 'bathtub curve' for failure rates if it's original.
Things I would check / do:
- Inspect coolant for deposits and buildup. Should change it regardless, but that'll tell you how much scrubbing or cleaning you have to do. If the coolant has any buildup at all, at a minimum, I'd back-flush the heater cores and put an OEM thermostat in. Aftermarkets have a smaller valve, don't work nearly as well. Rationale for heater cores is that the cooling loop on these relies on flow through them to actuate the thermostat. If they're clogged, you'll be chasing overheats. If you ever want to bypass them for any reason, then the way to do this is to get a U hose and connect the input/output together on the water pump. Do NOT try to block it off.
- Inspect soft parts. Belts, idlers, hoses, brake lines, brake pads, CV axles, ball joints, suspension bushings, etc. Replace as needed.
- Check transmission fluid with the vehicle running, hot, after driving for 15-20 mins. Consider changing the fluid. Exclusion criteria is: burnt smell, or particulates floating in the fluid. If neither of those exist, give 'er a refresh.
- Change fluids in general. Give yourself a clean start. Engine oil, transmission fluid, diff fluid, t-case, brake fluid, power steering.
- Plug an OBD reader on there and see if there are any pending codes
- Give the thing a general once-over. Check for fluid leaks, interior leaks. Make sure bulbs work, weather seals are in good condition, brake pads/rotor condition. Tackle stuff you find as you find it.
- Go get the alignment checked.
- Outside of general age related wear, common things on these vehicles are: differential issues, gauge-cluster stepper issues, oil sender leaks, transmission failure, transfer case pump rub, gross coolant, climate control issues (hot/cold and face/feet blend doors).
