JSB is an awesome color, and that is a great looking car! I have a cyber gray C6Z and I have always loved corvettes. As for the questions:
Price is so variable with these cars, and depends on a lot of factors. Trim level is crucial. More on that below. But you listed the mods, and the mods on it make it look great and there’s some value to them for sure. Those look like morimoto Headlights, very desirable and they cost 1400 by themselves. The stock headlights have always been one of the negatives in my opionon on the C6’s, they just don’t look good. But those morimotos are styled after C7 headlights and look fantastic. I want a set someday but 1400 for headlights isn’t cheap.

It’s hard to tell specifics from the pics but like you said there’s also an aftermarket spoiler, smoked side clearance lights (unsure if just painted or smoked or aftermarket LED or what) and LED taillights, can’t tell from the pics but possibly eagle eyes maybe?
If you're wanting an updated look, your solution is here! These Eagle Eye LED tail lights are brand new housings with the LED's already installed. No need to open up your stock housings and add parts to them. Simply remove the stock tail lights (held in by one T-15 screw) and plug these Eagle...

The wheels look like C7 Z06 wheel style, probably repros due to the offsets but I’m no expert. If they are actual original C7Z wheels they have been known to crack sometimes and have issues, just fyi. Good tires for these cars are not cheap, can’t remember if you said what condition they were in.
Trims are extremely important for pricing, earlier someone mentioned a trim level in their corvette, but if you look at the interior features of the car you might be able to figure it out and it might impact the values you’re seeing. 1-4LT on the base models. See this link:
When the C6 Corvettes were released, they had different trim levels. This article points out the various trims and what they may add or s...

If you’re really looking for info on all things (including pricing) on corvettes then that above link to the corvette forum is a fantastic place to start. Click on the forums tab at the top left and go to the C6 section and C6’s for sale and find what you are looking for or similarly optioned cars and see what they go for. I lurked there for years learning and checking pricing before I bought mine and it really helped me to find a good deal and make informed decisions. Same reason I’m on this site to learn about these specific skill sets and equipment. Just some suggestions.
But the car you are looking at looks great and has some nice mods that aren’t cheap. Ultimately, what’s it worth to you? Whatever you decide, once you get one enjoy it!
