Welcome Y2K,
How comfortable are you with detailing. With such an awesome car, it's not exactly one that you'll want to experiment on I would think.
The picture above makes it seem like it's pretty nasty and one that probably can't be corrected with touch-up or actually, a repaint as it's pretty long and many little lines which will be very very tough to spot correct.
If you think it can be corrected without a repaint (compounds etc.), and your not comfortable - then I'd take to a pro (ask a lot of questions before hand) simply due to the value of the car.
If it can't be corrected without a repaint, then prehaps trying some touch-up, wetsanding, compounding and practice a bit wouldn't hurt. Worse case, you repaint which was already a given at that point. Who knows, maybe you can actually make it look a whole lot better.
Try some scratch X with a terry towel (for extra bite) and see if you can make it look any better. You may get some hazing from the Scratch X - which can be removed with an SMR.
