Wait 5 minutes, and someone will ask what their Corvette block, cylinder head, water pump, etc. is worth. Answer: the same as the ones in that 4 door sedan.
The Corvette-only intake and exhaust systems are the only very $$$ parts, now priced far beyond their worth for performance use.
Just my 2¢?
Things that can only be appreciated when the car is parked with the hood up have minimal cost/value basis for me.
