Well...let's see...the first ZR1 went for a cool Mil...so I am going to throw my guess into the ring at $425,000. 1 of 1 and the ZL1 moniker are going to drive this one high.
Congrats to the lucky buyer. AND GM...Thanks for helping out a charity. Very Cool.
Cars and women are both going to give you problems...but you can pay somebody else to fix your car!
