What's my car worth?

The car has modded exhaust, intake, Unichip, boosted fuel pressure, a little headwork,(passes smog no prob) along with Supra TT suspension, and brakes with Bilsteins, 17X 8, 17X9.5,w/new Falken 451 tires.
The car is in all around great shape, has been garaged, one tiny door-ding.
I was thinking around $7K-$8K, but any ideas or insights from the forum would be welcome.
