 "Rome wasn't built in a day" and neither was Dave Hoekenga's 1965 GTO. Like so many of us, Dave fell in love with the '65 and that passion fuels him to work on it as time and money allows. Dave's car is a "I did it" frame off restoration. He's painsakingly done just about everything himself...and he is to be commended for it. His labor of love is in its' eighth year and still going strong. Dave plans to show the car this year at several Michigan car show events!

Dave's GTO was really a mess when he first got it, a real eyesore according to him (and his neighbors). In fact, the sheet metal was so bad that he eventually scrapped and replaced all of it with better body parts from another '65. Only the frame was saved and provides the foundation for the strong 455 motor. The car's exterior is GM white. It is a base coat/ clear coat system that he and a friend applied. To get that show car lustre he spent over 50 hours wetsanding and buffing the finish. On the inside Dave installed the headliner, carpeting, new dashpad, and painted everything else in gloss black to match the seats and trim. The stock console is slightly modified to accept the B& M ratchet shifter--"a lot of work but worth it,"says Dave. He also laments, that he wore the hats of a mechanic, bodyman, and electrician to avoid paying the "big money to get it done." Well, in eight years of wearing these hats, he's learned a little about Pontiacs and is a good source to contact if you have a similar project contemplated or underway.

By the way, this cool '65 GTO is streetable, as the tech data below indicates. Performance is impressive as well. If you have questions or curious to learn more, feel free to contact Dave Hoekenga at:
