Oh man, there's not a lot of love going on in there. If you're game take the mats out and give them a hit with some spray on sugar soap and then...use a high pressure cleaner on them . Obviously don't have it on a single jet or it'll cut those mats into shreds - just on a wide fan and use a sweeping action to lift all the goodness out of them. Couple of rinses and leave them somewhere flat to dry and they'll come up nice and fresh. After giving all the interior trim a good wipe over break out a can of cheap@ss tyre shine and give everything a light spray and then rub the stuff into it with your bare hands (it will take a couple of goes before it comes back to life). It will go a long way into rejuvenating the plastic and vinyl back to its former glory (however don't use anything to restore the trim if you're planning on going all Mad Max and recolouring it with a vinyl/fabric spray - it will make it hell to remove the silicon spray and the new colour won't take to it very well) It's a shame the radio wiring loom got butchered - it is sooo unnecessary to cut them up Post up pics once your interior is clean!
