realistically you will not find a genuine trueno for under 10k.
a 4age converted ADM levin will set you back 5-6 for a decent example.
a 4age JDM genuine levin is in much the same price bracket as the trueno.
although your signature mentions you want: no rust, no cracked dash, and prefferably white with good paint.
honestly, i cant see you getting a 4age converted adm levin with good paint, no rust and neat interior for under 7 or 8k depending on other mods.
do some research intially as to what your state allows you as a P plater to own legally, and then decide on a budget.
budget budget budget.
unfortunately it is the thing that cuts down so many young kids dreams of ever owning an ae86.
and hell, if its your first car, get a ke70. learn to drive it. dont worry about crashing and having a huge repair bill. it makes life alot more comfortable.
