What is it Worth? - 02 c5 z06

I'm considering selling my 02 C5 Z06 and building a single turbo Z28. Here's the details

02 Z06 23,000 miles

@5,000 miles:
Ron Davis radiator/engine oil cooler
T1 front and rear sway bars
Braided stainless brake lines
Transmission cooler (Similar to Doug Rippie but can't remember the brand.)
Brey Krause harness bar
Breathless Performance short throw shifter

@19,000 miles:
Ported 243 heads with Patriot Gold springs From Lloyd Elliott
231/235 .617 .621 Cam
Texas-Speed ceramic coated long tube headers
3" catless x-pipe mounted to stock Ti exhaust
39lb/hr injectors
Vararam intake
4.10 differential with all new seals and bearings done by DTS (The best guys)
SLP underdrive crank pulley

The car makes 430 rwhp on a loaded Mustang Dyno. It's always had Mobil 1 in the transmission, engine, and differential. No rips, burns, or holes anywhere in the interior. A few scratches on the outside. It's a very fun car to drive. It corners amazingly and runs door to door with my buddy's 603rwhp whippled 03 Cobra.

I'm considering selling and not sure what to ask. According to kbb.com perfect condition would be $27,500. I don't feel it's worth that exactly. But, I would obviously like to get as much as possible so if anyone has anything feel free to chime in. Thanks, Tim

Tim, with those low miles that money would be very realistic if not for the mods. You could still get it but it isn't as likely. No harm in trying, right? You will probably end up in the lower 20's range (under $25,000) and I wouldn't turn down a solid offer from a serious buyer. Your buying market will be very limited at higher prices unless you get very fortunate. GLWS!!
