I'd be a bit concerned, would have to see it run and drive it for at least 20-30 minutes for me to consider buying it.
I would also assume the following costs would be considered or repaired prior to purchase or the price lowered for such:
Wires, plugs, fluids such as oil and filter, transmission flush/filter, rear end fluid change, tires, check brakes and flush fluid, belt, battery, wipers, all the rubber hoses and vacuum lines.
Any options not working due to corrosion etc. repaired.
Lots to consider PRIOR to purchase and who will pay for it.
Buying it as is in not running order deduct plenty for the servicing and risk of it costing a ton to get up and running, regardless of the mileage on the motor.
Could also be 138K miles as well, check Carfax and look for other high signs of mileage on the car.
