Dude...you can always fix up the car later, or another car in the future..I have owned my 4g4d for almost 9 years...it wasn't until just a couple of years ago I knew anything about modding my baby..
Also, if you don't mind hearing my $0.02, and you can do whatever you want with it, the struggle to get thru school is worth every penny and pain in the ass exam to get that degree...Then you will be able to afford to do whatever you want... Stuggling your whole life sucks,

so stay smart and finish school
