The manufacturer tells us we can complete a kit in 160 to 300 hours. Not so for the average guy. It took me over a 1000 hours to finish mine but that was before Club Cobra and FFR forum. If you take 300 hours and divide it by 4 hours a week, it takes for ever. It's hard for a guy with a family and working to put in 20 hours a week on a hobby. I remember my buddy calling me up and asking if we were going to work on the Cobra today. I would get up and go work for a few hours. Those hours add up and after 28 months I had it on the road. I did work out of town 14 months of the 28.
The best thing you can do is find all the Cobra guys in your area. They will keep you motivated.
After you finish it you can go back and spend 2000 hours changing everything
