Should I buy a 1995 Taurus with a 3.8L engine?

I've heard these engines have head gasket issues. The car has 167000 miles on it and I don't know if the head gaskets have been replaced already. The owner doesn't have the maintenance and repair records even though the car is in immaculate shape inside and out and has all the telltale signs of being maintained impeccably. It looks almost new. (And for a 16 year old car that's pretty good) It has a set of 4 brand new tires. The asking price of 1350 is about 500 below bluebook for this car. The car is currently registered and passed smog and has a clean title. I took it for a test drive and it runs smooth. I inspected the engine and the oil. I even did a carfax report on it...everything checks out except the head gasket issue with this particular engine. I'm not inclined to gamble on reliability, but I've been looking for a pretty long time for a car and it's getting down to crunch time...I can't keep spending money on a rental to get around. Everyone tells me I'm being too picky, but when you live here in California you have the added concern that the car needs to be able to pass smog and there are so many cars that are for sale here that can't pass smog. If the head gaskets in these cars are so bad, then you would think this one would have blown way before 167000 miles.
