I actually took care of the interior TEMPORARILY last weekend..
I did a custom package tray with tan suede and installed a stereo..
I covered the seats with mexican blankets i found online and purchased.. before and after pics of the back seats below...
BEFORE Package tray.. non existant..
AFTER...
BEFORE Backseat.. front seats were worse.. I just used hog rings and added some padding..
AFTER Backseat.. Mexican blankets.. much better.. temporary cost effective fix...
