I recently replaced everything in the interior and all up it cost a bitover $7k.
This includes new seat covers, seat pads, carpet, inner door panels, soft top lid cover, dash, sunvisors, underdash panels, kick panels, windlace, headliner as well as new window winders (with new inserts), and lots of chrome (eg inner door panel top chrome strip, inner sill covers, etc, etc)
This also included new steering wheel & auto shift knob, plus new seat knobs.
I originally was just going to renew the carpets & seats. But once you do that everything else looked very poor ! So now, just my wallet is poor..........
