Uni-body and rear end

Hey guys,

My bro has a 1990 Lx, and thinks it has some major problems.

Apparently, he thinks the uni-body is 'bent'. I guess it must look scrunched like
an accordiane or something.

He also says the his rear control arms aren't symmetrical on both sides.

Does anyone know if these are 'normal' conditions or if his car really has major
problems.

I really don't want to see him sell it, as it has only 85k original miles.

Thanks.
