Tranny....its a weak point.
I bought a 97' with only 60k and every thing seemed tight. It was from an airline maintainance guy and it was in perfect shape.
In the first month, the transmission went. There were little to no signs when I tested it. Fluid was good, records were all there.
I would recomend, standing on the break and torquing it up a bit and see how the tranny shifts after that.
The transmission guy showed me all the parts and said someone had been racing it. It had the markings that someone had been slamming it into drive.
I have a 97 and I would definately go with the 98. Some of the bugs are worked out. I've got 91K now and I've had to replace the outer tie rod ends and now going to have to replace the right inner tie rod end. Ending is still great though.
Good luck.
