honestly, $25,000 can buy you a sweet car thats already built.
eg: my R32 cost me $13k !!!
why not save up and then buy a ready to go one??
but then again, building a car is an experience... hard to say if its good or bad (we all know about my EF XR6T lol)
$25k will get you a decent way with a build... how fast are you looking to go?
because you can get 11s cheaply, 10s a bit more, but single digit times... yeh bulk coin... if you want, i can PM you a list of my expenses as of 4 months ago (yeh bit slack), but im aiming for 7s/low 8s .. so different paths i think
