Being that I have an '00 GT Vert, I suppose I should have an opion. As far as looking for things particular to this car/year while shopping...nothing I can think of...just the usual issues with any used car. I would agree that the weak link with these models are the following:
- IAC (Idle Air Control Valve)
- TOB (Throw Out Bearings) (5 Spd)
Look for mods. If stock, fine. But avoid anything with an after-market MAF (Mass Air Flow sensor) such as the popular C&L MAF UNLESS the owner can produce a dyno sheet. Best, safe mods on that car would be subframes, strut tower supports, gears, and pullies (even pleum and TB are safe too). If you find one with more extreme mods, be sure to ask lots of questions.
When you start the car, pay close attention to how it idles. It should run around 650 - 800 rpms when warm and with the AC off. Turn on the AC, the idle should jump up and them come down. When driving around, the idle may hang at 1,000 rpms, but then drop to normal range after a few seconds. This is normal. An unusual idle could be a sign of other problems such as a lean condition or just a bad IAC.
Play with the top. Does it come up and down fine? Can you latch it? Putting a little force to get it to latch is normal.
Hope this helps.
