Does it have a Solenoid pack or a distributor and distributor shaft?
My family has had 5 of the older Taurus's over the years. My daily driver is a 2002 Taurus, with the gutless 3.0 SOHC Vulcan engine. Those engines aren't powerful, but they run forever.
The Vulcans with distributors that made it to around 150,000 miles started having timing issues due to lubrication issues in the actual shaft of the distributor. The issue starts to show up around 75,000 miles, but really comes to light by 150,000 miles.
The fix was to replace it with a more updated design, it's a known issue, and is a serious undertaking to replace.
Go over that car with a fine tooth comb if you choose to have it. It could be good, or it could be bad.
Like many cars, it all depends on the previous owner.
I'd personally worry about it surviving so many Pa winters and having more rust than steel left in it.
