What's it Worth? 1989 GT - What's it worth?

I'm considering selling my 1989 GT and I was hoping to get some feedback on possible price. I've done a lot of looking and prices seem to be on the rise but I'm not really sure what to expect because very little is stock on this car. The odometer shows 113k but it doesn't have the original engine, the entire thing was removed and painted when the heads, cam, and intake was installed. I'm assuming it's a stock bottom end with nothing fancy in terms of rods, pistons, etc. It's always been garaged and never driven in the rain. There are no issues with the car at present and it's rust free. I have copies of all the receipts and a notebook with my maintenance log. Thank you in advance for looking. This forum has always been extremely helpful.
