Well Jhollands just sold his mint 05 ba ute for 20g and that thing was bangin! If you can play the waiting game there will always be a few bargains that pop up.
Depends where you live aswell mate. A manual high performance ute over here in W.A = $$$. Over east cars seem to be a dit cheaper. 20g will get you a well looked after BA manual ute with around 80-100 thousand km's.
