Default Valuation for insurance -- 2002 Z28 M6 w/ LS3

Hey folks! So, I'm putting the final touches on my LS3 build. Details here.

I'm excited to say that the time has come to insure the car for use on the road again! I'm talking to Hagerty, and they want a valuation. So, I'm here to ask what you guys think.

First of all, how should I approach valuation? Should I base it on:
  • the amount that would allow me to replace the car with something exactly like it? (cost of another car + all mods + labor to install)
  • the amount that would make me feel whole if it were totaled?
  • the amount that someone else would be willing to pay for it?
  • something else?
Unmodified, the car would be worth maybe $10k. Probably more if the paint condition didn't suck. I've spent easily $20k on all the mods below, and did all the work myself except longblock assembly which was done by a friend who is an engineer at Katech (not officially "by Katech", but using their facilities). It took me six years worth of spare time to do everything. I imagine a pro shop could do it in a week or two, assuming parts are all on hand -- so probably $8-12k in shop labor on top of that to recreate it. I don't think anyone would pay even close to $40k for the car, so there's a big difference between fair market value and cost to replace.

If you care to cast an opinion on what value I should actually use, here are allllll the details. There are lots of photos in the build thread linked above.

The car:
2002 Camaro Z28
T56 w/ Hurst shifter
Navy Blue Metallic
T-Tops
Ebony leather interior
Preferred Equipment Group (cruise control, power seats/windows/mirrors/locks, etc)

Condition:
120,000 miles
Mechanically: excellent
Paint: poor (chipped in a few spots, two very amateur DIY patch jobs)
Interior: good (seats not torn, dash not cracked)
This has been a Michigan car its entire life, but it has never been driven in the winter or on any salt-treated road.
There was some rust in the upper front suspension mounts, but those have been completely replaced.
There was also some rust below the battery, but that area has been painted with POR15.
Typical surface rust on the bare-iron rear axle. I plan to paint this with POR15 in the near future.
Everything works!

I am still working on the tune and don't have dyno numbers yet. I'm expecting 550-600bhp, which should yield 475-525 at the wheels.

Sounds like a fun car. I also have Haggerty, and I based my value on what it would take to replace my 1999 TA if it gets totaled. I based my value on the appropriate market value, plus all the extra upgrades I have done. I can't give you a price, but add up the price to buy a decent fourth gen Camaro, plus the money you have invested in it. Just my thoughts.

I have agreed value policies for my garage queens as well, with Grundy. IMO, some combination of the following two things would be the only factors that would matter to me:

But this is the one factor that wouldn't even enter my mind:

With an agreed value policy, you don't need to concern yourself nor feel restricted by "market" value. That's the trouble with "normal" insurance on cars like these; they will never pay you what it would take to duplicate a creation like this, but the whole purpose of an agreed value policy is that you can eliminate that risk as long as you meet the qualifications of that kind of policy.

Thanks guys!

The agent suggested a value of $30k. Not enough to recreate it from scratch (that’d be more like $40k), but enough for me to move on, I think -- and likely also enough for me to fix it, depending on the damage. I think I’ll proceed with that.
