My word. Get the money from a family member, rob a bank , sell your little brother ...at that price at the end of the month you still won't have one .... someone else is going to knock him down giving him the money .
Is a non rusted low mileage , non molested Rubi worth 10k? No , it's worth 13-15 is what it's worth, all day long .
Don't even take the time to ask us ...that TJ will be gone quickly.
Also , as a reference point , that TJ versus what you have is a stud. Not knocking your current TJ, but a Rubi is one of the most capable off road vehicles ever mass produced.
