“......When you get to building a car for 8 years, come talk to me.....”
I’ve been doing my 37 Dodge pickup for 10years LOL, actually though in fairness after I got the first mockup done I set it aside for several years and did some other projects, I just got back on it recently.
I usually have the cars pretty well planned out before I start on them and usually stick pretty well to the plan.
The Dodge has been a bit of an exception. It was initially going to be a street rod with things like cruise, AC, power windows etc. Somewhere along the way the plan changed to built it as an all out hotrod and put the money into the drivetrain (screw streetability and creature comforts). I’m currently redoing the mockup.
