it looks like it has been lightly modified, i would take a close look at the fluids and the whole engine as it may have been abused. if everything seems ok on the test drive and the fluids are all full and good color i would then ask for a maintenance history or some evidence certain items have been changed such as the timing belt and water pump at 120,000 miles is the max for changing the timing belt and you should always do the water pump while in there. check the cv axle boots as well, then check some suspension components such as tie rods ball joints ect. i would say take it on a test drive and take it to a shop you trust and have them do an inspection before you buy.
