After a year of working on my Mustang, if I knew then what I know now, I'd still tell you you're probably getting in over your head with that car if you decide to get it.
Money + Free Time X Hard Work + Patience ^2 = Finished Car
The (^2) means squared by the way. You might not have had that type of math yet, but it comes out to be a really really really big number.
I hope the advice you get doesn't make you upset or disappointed. We are just trying to make you aware of the sacrifices you will have to make, before you make them. You can judge whether or not the purpose for that sacrifice is worth it.
Whatever you decide, good luck Kid.
