Took a 99 T-5 wagon off a lot for a test drive. At ten to fifteen miles an hour with three people in it, when I romped on it the car started to pull sideways on drive asphalt as the wheels came loose. You could feel it. Impressed. The next day I test drove a beautifully maintained 97 850R wagon with only 50K on it. Again, with three people, when I romped on it it didn't seem to have much more acceleration than my 97 850 GLT wagon. A long ways from the tires breaking loose like on the 99. I thought the 850R would crawl out from under us like the T-5 did, but absolutely not. My question is: Would a 99 T-5 normally accelerate the way I described, or did it possibly have a performance chip in it or a different torque curve? I can't believe there was such a difference between these two cars. Dick
