Price is decent for the miles, but the condition is fair...just from pics it looks like the front bumper is roughed up, the driver's seat is worn, the steering wheel needs replacing...but most important is the mechanicals of the car.
Engine, transmission, rearend, braking etc..all those systems/components should be checked out thoroughly before buying. If there's some minor mechanical issues like belts, filters, or even a fuel pump needing replacing, then I'd say still get it, those fixes are doable.
In 2000 there were 2 green options: Electric and Tropic..I'd say this one is Tropic as that's the darker green, Electric is much brighter.
Also, it looks like the car has exhaust and the hood scoop was added, as the 99/00 regular GT's didn't come with hood scoops.
Hope this helps and let us know what you decide
