i started to build my ute when i was 14 and yeah, i know whats like when you are strapped for cash. i still am pretty tight on money and i only earn bout 130 a week.
best thing you can do would be wheels and a nice ride height, it will cost you about 300 to lower your dato if you fit the parts, ebay sell lowering blocks 2 inch for 70 i think and king springs do a super low 2 inch for about 230 i think. as for wheels just have a look around and see what pops up on the fourm. heres a link to my ute
