It's tough to say. We don't do as many headgaskets as we used to, but here could be several reasons for that. When we first started adding the conditioner we had at least a dozen cars that came back within a week or two because of overheating problems (search the forums for my posts on conditioner problems). They all had radiator failure (surprise). There seems to be two major keys to putting the odds in your favor: 1) the conditioner has to have been added in a timely matter. We have people who are still coming in for this campaign, a whole year after they became eligible. The higher the mileage is when the conditioner is first added, the lower your chances are of it working. 2) It is VITAL to follow the directions on the conditioner. We suspect our radiator woes were caused by a tech who was rushing through the job and not following the directions to the letter. Since then, we haven't had any come back with radiator problems.......but some do come back with headgasket leaks. Within the last 3 weeks we have performed 3 headgasket jobs on cars that have had WWP-99 completed. And that's just the last 3 weeks.The good news is that after having WWP-99 performed Subaru will extend the warranty on headgaskets to 100,000 miles. The bad news is that Subaru will only authorize the replacement of the headgasket that is leaking. That means that if only one side is leaking you could very well have to come back within a few months to have the other side taken care of

As far as buying that 98 GT....great car, but check to see if its had headgaskets done.

I just noticed that your car has 99K......that means your headgasket warranty is only good for another 1k
