If you ask me, I think it would be much easier to swallow your you know whats and plug it out with what you have, and save up for the lightning. I'm 17, and I know what its like to have a short budget, but you have to look at it this way, you dont have much of any expenses, and if you keep them down, working a part time job, you can afford it soon. I started working a little at 15, and started working a big at 16. I do not spend much money on anything else but my truck. I have a 95' F-150 Eddie Bauer that i got for 8500 bucks and it is in really good shape. You'd be suprised how the 150-200 dollar paychecks add up each week. good luck!
