Today we finished up this one owner 68 GTO that was purchased new right here in Selinsgrove at County Sales Pontiac Cadillac. The same place my dad bought his GTO's.
The GTO was built at my friend's shop 20yrs ago and rarely gets driven. We just went through it front to back, changed all fluids, penngrade1 oil change, new tires and went through the fuel system. Sad to see it go, but happy to deliver it on such a beautiful night.

Christmas morning circa 1992. I was 15 and so stoked we were having a white Christmas. Meanwhile my dad was secretly freaking out that my hidden present might not make it up the driveway. That green thing on the hood..trash bag bow! Cars were the only thing my dad and I had in common and years later I'm still realizing how special this moment was for him.

A few years ago I got called to appraise and authenticate this GT500, as part of an estate. What we found was a mostly original car parked in 1987 with 37k miles. We brought it home and did a preservation of the car and gave it back to the family. The last couple of weeks it came back in for an oil change and a health check. Such a cool car and we're honored to be chosen to maintain and preserve it.
