A little off topic?
Looks like this changed from a consideration of the GTO Solstice styling proposal, or if it is real, some information on who is or did this or if it's a Photoshop fantasy. Personally having bought a 1965 LeMans new back in 1965, having the family insurance agent talk my cosigning parent out of backing the GTO purchase, I would entertain this conversion just because. We can spend thousands on other Solstice body mods and get a knowing nod of approval.
This thread devolves into a discussion on new and vapor Corvettes. Check the December Car and Driver for more info on the 2019 ZR1. If I had the cash to afford a Corvette I would not worry about a water pump in the GXP. The little GXP rides almost as harshly as a buddy's Z06, but his is a pure track car.
If I missed the info on the GTO Solstice source, chalk it up to my new eyes using my old glasses. I know it's been exceeded many times in the last 50 years, but when I worked at Union Carbide electronics, one of the guys back from Viet Nam had a yellow '67 with all the options ticked off. The 427 tri-power with side pipes was a memory to walk by. Let's park 'em side by side and see who looks at what first.
