The guys are giving you terrific advice, not to discourage you, but to steer you in the right direction and point out the realities of building a car, any car.
There is a reason a lot of us take 4,5, 6 or more years to build a car, and that reason is generally money........and time. When you have the money, you don't have the time, and when you have the time, you don't have the money.
But finishing the car is anticlimactic to a lot of us, we just enjoy getting out in the garage and spending time, sometimes doing a little to the car, and sometimes just sitting in our thinking chair with a cold one.
Take your time, ask a lot of questions, and do it right the first time. The car will be safer, more dependable, and you can proudly say "Yes, I built it myself !"
Have fun.
